Yep! Our tech people are picking up on these people using proxies. Just banned another person for multiple accounts, who had also made comments on this thread.
From this point on, please only ask for a bonus if you have 10 activity or higher. It looks like some people have a decent size activity amount, and then creating new forum accounts JUST to wheedle multiple bonuses. To those people, I ask you to find someone else to try to con, otherwise it might be name and shame time!
