The promotion of mixers, gambling or casinos does not obstruct anyhow the discussion about Bitcoin, technology or crypto at large. Obviously, OP is too new on the forum and makes allegations without any sense. If OP wants to participate to any technical discussion he is always free to do it, no matter if the other participants wear any signature or not. How can the presence of a signature obstruct a discussion? I really don't get that.
I have a feeling he felt that there are too many threads/replies that are unnecessarily made because of signature campaigns and just ranted because of it.
Furthermore, and I don't know if anyone else observed this, OP just started this thread and never came back with any reply. It seems simply ridiculous to initiate a discussion thread, complaining about how to discuss
and then never make any post inside your own thread. I guess it's common sense to debate inside the topic you started, since it was your interest to start it but OP is probably lacking this common sense.
I noticed that when I made my first post in this thread but it was just the second day since the OP created the thread so I didn't think much of it. anyway, even if OP wanted to reply now he won't be able to since he got banned from plagiarising content multiple times.
