The forum has been under sustained attack from spammers over the last couple of weeks. Posts with links to porn, pills, all kinds of stuff. Many hundreds of posts have been deleted, many hundreds of new user accounts have been deleted.
I have done a couple of things which may hamper some of them.
First, no user may now make a post within 60 seconds of his/her last one.
Second, I have set a limit of 5 links per post.
These may hamper those automated spammers that post dozens of times in a matter of seconds, and those who post multiple links. I hope 5 links is an acceptable limit for most purposes.
I have also added to the questions for new users - when registering, a new user has to answer one question selected at random.my theory is that having a larger number of questions may slow down the machines that are pre-programmed with one answer for this forum. No 2 questions have the same answer.
