Yes, unfortunately we started to have this problem since we open this forum, but in these days, it's becoming worst. We'll be communicating with Nabble in order to they can help us with this disturbing problem.
We have banned all users with 0 posts and surely are spam users. We know it's very hard control spam, but we check out daily this forum, and every time we got a spam message, it's deleted inmediatly, of course sometimes, it delays when we're offline.
So, if you're going to register in the forum, please be sure to post at least one message in order to avoid be banned by us, thinking you're a spam user.
Sorry for this new rule, but this problem obligates to do it.
