Giving abusers the silent treatment

The subject of abuse comes up almost daily at Viddler. Whether we’re flagging videos as violations of copyright law, discovering users who try to distribute full films, etc. were always discussing ways of suppressing abuse.

Turns out that other services have similar problems of dealing with abuse on a daily basis. San Francisco-based Ma.gnolia doesn’t necessarily have to deal with the same issues that Viddler does, but they deal with an entirely different type of abuse. Where Viddler deals with users that upload content they do not own or that contains material that the service was not meant to host, Ma.gnolia deals with spammers that try to use Ma.gnolia as a way to build PageRank.

In both cases, though, the way each company has chosen to deal with abuse is much the same. Both Ma.gnolia and Viddler use a 3-step process: Hide, Wait, Delete.

Viddler’s flagging options

When we find a user on Viddler that has uploaded a video that violates copyright law, we’ll typically flag the video (the same feature available to anyone browsing the site), and hide the video by making it private. Sometimes, if we feel the situation warrants it, we will message the user asking them if they own the copyright or have permission to publish the content. If we do not receive a response we’ll delete the video. However, if we notice the user only uploads “spam”, that are in clear violate of our terms of service, we’ll will quickly flag and delete those videos without even asking the user. Usually these are cases where someone uploads three copies of Harry Potter and four episodes of LOST in one night. And so far, Viddler has done extremely well of warding off this type of abuse.

Ma.gnolia goes one step further. The moment that a spammer is identified their account is flagged as such. This automatically makes the spammer’s content (or bookmarks) disappear for the public Ma.gnolia community. Except, unlike the Viddler user that can see that we’ve make their videos private, Ma.gnolia makes everything appear completely normal from the spammers perspective. This is genius for a few reasons.

When spammers find a way to exploit a system, they’ll typically continue to do so until it doesn’t work anymore (or they’re blocked) and then they try to find a new way. If Ma.gnolia were to simply block that user from posting their content, they’d simply find another way to do so or open a new Ma.gnolia account. Instead, it might be weeks before the spammer sees no dividends from its effort to spam Ma.gnolia. Which cuts down the amount of “spam blocking” efforts Ma.gnolia has to make before moving to the next step!

The next logical step for Ma.gnolia is to delete the spammer’s account. They only do this after the account has been inactive for at least 6-months. When they do this maintenance they end up deleting millions of identified spam bookmarks at a time. Since we’re working on keeping Viddler very clean on a day-to-day basis the amount of data we “delete” each day is relatively low, but obviously we’re spending more time doing this more often.

I could imagine Viddler benefiting in a few ways from incorporating a similar system to Ma.gnolia. The first would be that we’d be able to save some day-to-day resources in marking multiple videos and instead just be able to flag accounts of known abusers. Second would be that we’d be able to quickly remove an enormous amount of content in bulk. And third, it’d probably cut down on the amount of “spam” that our community will have to actually see. This is definitely a note I’ll be dropping into the suggestion box.

Starting a new project where you know there will be abuse? Take note.

    On Band Madness, we would just do everything to make them miserable. The biggest problem we dealt with regularly was comment bombing, so we just set up filters to make it seem like they were saying the opposite of what they were trying to say. Believe it or not, people actually learned to have meaningful conversations once they realized that a flame war would be a futile effort.

    I really like the idea of being able to flag a USER, instead of all 60 of their spam videos, and then have them set up like Mag.nolia’s done, where they won’t know they’re being thwarted until well after the fact.

    Brilliant!

    Hey, thanks for this information, it’s great! I am working on a project where I know there will be abuse, but I was going to deal with it when it was an issue…this gives me a few tools to work with when the time comes. Thanks again!

    Chris: By “comment bomb” do you mean that people would actually be manually typing in tons of comments? Or, is this spam related?

    In Ma.gnolia’s case I think they see a bit of both. They see automated spam bots (due to having an open API I’m sure) and some where they just see people submitted spam-like bookmarks a lot. Perhaps Larry or Todd could confirm what type of ratio they see?

    With Viddler it is completely manual (as far as we can tell). But being that we have a bulk uploader it makes it fairly easy for abusers to queue up a ton of videos and just walk away.

    Brandice: I am not sure if we’ll give this “power” to the Viddler community, or perhaps only a select few people (also like Ma.gnolia’s gardeners). This is something we’ll have to build for ourselves internally first and then perhaps expand it to allow the community at large to do this type of thing.

    Randy: I’m glad you found some value in this post – this is exactly why I wanted to write it. I wanted those of us spinning our wheels to get a reminder of the best practices and anyone starting something new not to head down a path that could, potentially, waste time and energy.

    Thanks to everyone for reading my post!

    you shouldnt remove flame debates, people love to battle and argue. Its really fun. You have to consider free speech, just cause you dont like doesnt mean you should remove it. You have to respect free speech. I am, of course, NOT talking about spammers, they deserve it. I talking about flame debates like this vs. that.
