Spam attacks
Hi all,
apparently, the web site is currently under increased attack by spammers. Unlike with many previous incidents, some of the recent postings are fairly, uhm, graphical and unsavory. The moderators are trying to keep the forum as clean as possible at all times, but you can help us by reporting offensive postings, using the "Report post" tool (see attached screenshot). Thanks! Claus

Re: Spam attacks
It seems that the spammers have a new tool which can read the verification images presented during registration and auto-register to post spam. We had about 30 new registrations in the last 24 hours, most of them look like spammer names and Email addresses. I am banning all of the new members which look suspicious. If you are a legitimate new member and get banned click the Contact Us link at the bottom of any forum page and provide the member name and Email address that you used to register.
I have temporarily turned off new registrations to stop the flood and am investigating options. One option offered by vBulletin is to require new members to answer a series of questions when they register. Some posts on the vBulletin forums suggest this as a way to stop this type of spam attack. But I'm not sure what type of questions to ask. Ideally it would be something that anyone using CoCreate software would know. The question and answer are free format and the answer can be checked using regular expressions. Suggestions are welcome.

Re: Spam attacks
I did some more searching on the vBulletin forum and found some good suggestions for how to reduce spam bot attacks. As a start I have turned registration back on and also turned on moderation of new Registrations which means that an administrator must approve the request before posting is allowed. This will at least prevent these spammers from posting while we try out some of the other suggestions for human verification.

Re: Spam attacks
Only a big spike in daily registrations, no increase in views.
I have made some changes to the registration process which seem to have stopped the auto registration by spammers. I upgraded the forum to a newer image verification method known as reCAPTCHA and added a question which requires entering the name of any CoCreate application or product. It is tested by a regular expression which should match any past or present applications names. Hopefully this will not deter any legitimate attempts to register.
