Generally speaking every site has rules and there is no denying it. What you can say on one site perhaps is not permitted on another site. To your point regarding SP on telegram (past, present or future), if the proverbial dogs who are passionate about TTCM attack then one needs to bring their A Game I suppose. It seems as reasonable as any site to me. People passionate about the stock.
There is a separate Telegram group for SP discussions. The Founders Group is for questions and discussions as well as sharing ideas. These rules have been in place since the Telegram groups were instituted.
