If you try to insult them or make them realize that their opinion doesn't matter and we are fundamentally not interested in the same thing, they will resort to behaving in this irritating, know-all manner (signing off posts..LOL). Such preposterous behavior, shitposts all pointing to the exact same things and you can't help but realize that these people are basically just internet trolls. They say shit for the sake of getting some attention and are hardly interested in real discussion or agreeing to disagree.
The forum allows useless people like him to continue to operate because well, we are all Satoshi and we think you are entitled to waste your time, respect and dignity whatever way you deem fit. If it was up to me, I'd simply just ban a lot of these assholes after such repeated wastage of human interaction. Be thankful that the mods are only deleting your trolling shitposts.
Also, there are hundred of people doubting bitcoin on this forum. We all talk about how adoption and use-cases are the need of the hour. We discuss about possible social and economic ramifications and what they mean to bitcoin. We talk about the new technological add-ons been worked on by the open source community. So, NO, this forum is NOT about pumping bitcoin. Lowlife trolls like you cannot understand that. You are just interested in your stupid agendas. We don't need the likes of you, so yeah, FUCK OFF!
