I was exagerating about the bans because this is actualy an unenforcable rule. Only should a player/clan/regiment care to make a thread on these forums would they kinda subject to this weird rule. Let say if a NW regiment switch to HF and didnt even knew about these forums existance would it be ok to them to encounter players on servers saying "You cant use this name, I claimed it on the forums, its rightfully mine". Why would they care about what that player says? Why would they be required to make a thread to have a name in the game. What if some clan will use a name for some time without bothering to register here or make a thread and then some months later would another clan with the same or similiar name come in but make a forum thread. Would the first one loose the "rights" to their name? Sounds like nonsense.
I may be used to a different forum culture, but usualy bumping a thread is frowned upon.
Maybe if the community is not able to be mature enough to have threads about their clans without bickering who got it first, then maybe make the crew forum section heavily moderated, allow only informations about the clan and dissallow any discussion in their thread. Might be severe, but it works fine on the ArmA 3 forums.
