That's bad and the hashtalk strict censoring is perhaps one of the biggest red flags IMO.
As of late anyone who provides any constructive criticism, asks a legitimate question (such as yourself) or lets just call it what it is, isnt a GAW cheerleader is banned/shadow banned or has their comments deleted.
Listen even though we all have our suspicions nobody truly knows if this whole "Paycoin" campaign is legit or not.
-It could be the next big thing.
-It could be a great idea but ruined by incompetence/arrogance (most likely in my opinion)
-It could be a huge scam.
But when you censor anyone who provides any sort of doubt or raises legit questions it screams stay away or get the hell out while you can.
It actually is not a red flag, at least to me. The forum is not a requirement, only an option and you have to know and accept their rules when going there.
If you don't like the restriction you can use it to read the announcements and don't have to write anything.
What if I made a forum that had in the rules "posting pictures is not allowed" and you started arguing that all other forums allow it and I banned you for it? Would that be my fault or your fault?

You don't think addressing your customers concerns by removing their posts is a red flag?
Does it say in their rules that you must agree 100% with what they are doing and never question anything?
I'm not talking about people who are just blasting GAW or are doing nothing but trying to spread FUD. Yes those type of posts need to go.
I am talking about people with legitimate concerns who are voicing them in a constructive manner and their posts are being deleted or their are banned.
