Because you are posting crap.
I posted awhile ago and then when i checked again it was deleted
Why are you complaining? You were just posting in those crappy threads that are like "Bitcoin in 2 years" "Bitcoin for your momma" and so on..
Why do they need to delete it? My post/replies are related to the topic and threads though
It is your fault, if you were really trying to contribute to this forum, you probably would not be posting in those shitty crappy threads, because they are innecesary and they do not bring anything new to us, only spam and signature spamming too.
