Problems with visitors

This is getting exponentially worse..

I got an idea from this2 thread.Admins should introduce blacklisting.They can give blacklist rights to users who have atleast N posts.And when a post gets atleast X blacklists it is removed automatically.Is it possible to implement this ?

Posts by spamers mentioned before has been removed. Thank you for the hints.

A new spamer called "yj1tm2pl3" appears.

Thank you.

thanks!

Another one. User cdef043 has posted many spams in the same forum.

thanks!

I think Mr.HASSAN01 is drunk or something. He has posted ads in the 'Problem Set Archive' and in the 'JAVA Based Languages' section.

I've deleted his (spam) posts. Thanks.

Well, another one named ARCLINKS has posted spam ads in C/C++, functional programming and off-topic sections.

It happens nearly daily I just normally delete them before anyone else sees them.

we look carefully into it, thanks!

Is this bot (zyzy4455) could be "destroyed" ?

This one was worse than normal. Most spam you never see because I am on here a lot and they normally make one or two posts. Unfortunately this one made 100 posts. I don't have the capability to delete more than 1 at a time.

I have appealed to the admins for assistance.

It flooded my gmail inbox too ( notifications for new posts in threads in which i had responded ). Admin should have privilege to mark a user as spammer and automatically delete all his forum posts.

I can ban them, just not batch delete.

I subscribe to the entire forum. I got all 100 emails...

Would this be considered spam?

Yup. There was a time where I would see about 20-30 of those posted a night.
