Using SQL and Python, I dug up some 40-ish forum spam comments, oldest of them are from 2013. How should I report them? I can PM the list to any mod who wants to tackle them.
I’m sure there are more than those 40, it’s just that Derpi has over 5 million forum posts, and no matter how you filter them, there’s always too many left for one human to review. The most effective filter is to remove all posts made by users who have made more than one forum post or image comment, since most spammers only make that one spam post. The second important filter is to include posts that contain an off-site link. That second filter can be refined by whitelisting numerous “safe” domains, like common news sites, Wikipedia, etc. Combined, those two filters yield wonderful results, but there are still too many for one human to check. They have to be manually verified, you want to minimize the number of false positives.
