Since I have been a member of this forum, I have made many comment about the Bitcoin scaling problem, and virtually none of them have "toed the party line". I have received many critical comments ( probably all justified), but at no time have any of my posts or threads been censored. My comments were made almost immediately as a newbie and though my ranking until fairly recently. I did receive a considerable number of helpful and knowledgeable replies from the established and well informed members here.
I'm not sure how they can justify a comment about excessive censorship here. In my opinion, there isn't enough.
The comments in the article about bitcointalk are complete nonsense.
There is no censorship on here. Even scammers are not censored.
There are rules that you have to abide by. Like no posting of off topic subjects.
I don't know about reddit because I do not post in that sub reddit.
I challenge them to show one deliberately censored post on bitcointalk that didn't break any of the rules.
