It seems I can still bet on eliminated teams of the Uefa Champion's league is it a visual bug or I really still can bet on them?

If you really want to go ahead and bet on them.
I am not entirely sure but isn't this topic self moderated? I mean if it is not that this dude can bug us all and get away with it which is really horrible but if it is self moderated could you please delete his future messages and not make us deal with it, I mean it is obvious that he is either a troll or really an idiot. As a customer it really bugs me to see these type of people flock to freebitcoin and bother you guys because it just takes away valuable manhours to deal with them.
He is really going to just spend all his time to take away manhours from you guys to actually have that 400+ dollar back from you, not in cash but in time obviously. Its just not ideal to have any complaints of course but even someone who even the people here do not even care is just better than having a real serious problem but worse than no problem

. I hope he shuts up soon.
I do sympathise with how annoying it is for everyone else. Using a self-moderated thread isn't the way to deal with it as it gives the impression that there might be something to hide. This way everyone can see the guy is just a complete idiot. I highly recommend using the ignore user function on the forum so you won't be disturbed so much.
