Default Spam prevention: Posts from new users will be filtered for spam

Hey all,

Due to a continued increase in spam, which has ranged from the most subtle to the most *ahem*...graphic, I just activated a filter for posts from new users.

This will subject new user's first X posts to screening via a stringent third-party spam database, and hopefully weed out the remainder of the spam I can't catch manually.

If for some reason your posts aren't making it through and you think they should, please send me a PM or email. I expect to have to work out some kinks.

Thanks.

And a good idea. Yesterday's posts were definitely NSFW (not safe for work). Actually they weren't safe for home either. It is a shame that our beloved site got hit that way.

Bump for not needing to modify this setting for 6 years.

There's another one that just popped up. Seems to be largely throttled at least.

This one literally asks to be banned under "instruments".

Still seems to not quite be working. Though, most of the spam posts now show up as "moderated".

Seems to be only one account (slowly) getting through at the moment. Depending on what permissions they get, you might want to just deputize a few more moderators.

Another possibility, at present, is to prohibit the use of non-ASCII unicode characters in new posts, if you have that kind of flexibility...

Looks like the bots are working through the new "300 seconds between two posts" limit.

It's a lot easier to clean up, though.

Also slightly more intelligible yet useless spam like this:

I am working on installing a totally new spam protection, probably when I upgrade to vBulletin5...

Yeah, this is a stopgap until I have a better system...

Thanks guys for bearing with this...I know it's annoying. We are getting hammered lately...

I guess I'll volunteer, since at least that will spread out the time zone coverage a bit. BTW, the spammer seems to have gotten through somehow.

I'm also willing to wield moderator powers for banning the occasional spammer.

In the meaning the 300s rule means 5 minutes between posts, which sadly blocks my usual pattern of scanning the forum periodically and answering a batch of questions. I hope this stopgap can be replaced...

Perhaps introducing "captcha" for first 15-10 posts would eliminate bots?

PS: I'm unsure how easy it is for site admins to introduce any new feature based on time, and financial resources.
