Telegram is full of scammers and impersonators as well as spammers. It is hard to get important information in crowded telegram chat group except checking their pinned messages.
About scammers and impersonators, on Telegram, I changed my account settings, to restrict strangers to add me to their scam groups. Furthermore, I also create a folder is named as Spam to filter all DMs from strangers. I usually never check that Spam folder that I believe help me to reduce my exposure to scammers.
I did not know that the site had a telegram where you can access pinned messages and participate, what I want to ask you is if there are many who send spam msgs there? I don't like many telegram groups for that same reason, they are very annoying, when they realize that there are also women they start harassing them and it is difficult to get rid of them, apart from that group they do not have a channel where they only give announcements, information about the place.I was in a telegram group a long time ago and the guys who write are sometimes very intense, and what they do is look for something other than gaming.
