This last blast we had was really huge, it lasted almost the whole day. See: https://i.stack.imgur.com/OXvpc.jpg
I have noticed across SE we are getting a lot of spam, usually titled "WATCH BLAH BLAH BLAH HERE".
It is very repetitive, regularly coming in the later afternoon/early evening (pacific time) a few times a week. This is starting to become a problem (on Ask Ubuntu at least) because this spam comes right when things start to slow down in the evening. The spam has actually stayed long enough, that when I check review in the morning I've seen it in in first posts.
What can we do to
Help prevent this spam in the first place?
Make sure it gets deleted faster?
Several thoughts on the subject:
It doesn't appear to be a bot, unless it's a very smart bot. I've seen the "OP" of these spam posts edit them and he once even posted an actual question about this "movie" and added legitimate answers.
As you can see in the one below, he asks where he can watch this movie, and then adds spam answers with links.
He can be pretty steady too, flooding the front page with these.
I've seen this spam on Ask Ubuntu, Security.SE, Ask Different, Smug Mug and Drupal. The spam on Smug Mug lasted several hours at least.
Possible problems I see currently:
Very few of these posts get more than 5-6 downvotes, and almost never get enough flags to disappear on their own, meaning they can be around for a long time.
Getting a score of -4 hides these questions from the main page, making it harder to kill them.
This might be a good thing, nobody will see them until a moderator comes around, but it also takes longer to delete them. The longer it takes to delete them, the more the spammer usually posts.
Possible (maybe?) solutions:
Blacklisting the links in these posts might help prevent them from being posted, but I've noticed they don't seem to all have the same link, so our mileage may vary there.
I've heard that if it got bad enough, SE might consider blacklisting an IP address. I don't know if they still do this or not, but it certainly seems like there is only one spammer behind these posts.
Thoughts based on comments
Spam chat room
This would really be a good idea if we can get people to hang out in it. If we could get people to hang out there, what chat site would we put it on? SO chat, MSO chat or SE chat? Seeing as they don't integrate well together.
Well some more spam came around this evening (It's actually still there... waiting for a mod). The spammers got even trickier, adding tons of whitespace and
<br> tags, making the post so long it hid the flag button. I almost didn't figure it out, but I had read a post (I think it was here on meta) about this and quickly figured it out.
