We have been getting hit hard by Russian, Ukrainian, Chinese, American and Canadian spammers lately, it is difficult to keep up at times when 10-15 register within 10 mins of each other. I/we have to go through each user and verify that they are indeed a spammer, this can sometimes mean waiting until they spam the boards since it MIGHT be a legitimate person but on average it is an easy check by looking at their emails, quite often they use ones already blacklisted. Just keep reporting the posts you see and dont bother replying to them for they are just dummy accounts that no one replies to. Thanks!
