There is a version 7.6 of the UBB threads - but they're not doing development on this forum software anymore. Regardless, It's likely that this older version still has an option to turn on an option to require new registerees to type in a letter/number sequence on one of those fuzzy pictures in order to register a new user name. That alone should keep the bots out.
I have a UBB forum and every applicant must be personally approved by me. It is pretty easy to spot folks that do not fit our profile.
It is also pretty easy to go in and remove any of those posts such as we have here.
