Is this an official Telegram account affiliated with BC.game? Or one of those?
I've seen it spamming messages on some groups. While I'm sure that it wasn't affiliated with BC.game, since as far as I know, their Telegram channel is a notification group plus local groups, I just want to verify it here.
The account has a subscription in Telegram Premium and has a premium badge on its display name, making it look legit.
It is easily to know whether it is an official account or not.
Visit BC.Game website, and look at a bottom right, you will see "Join Our Global Community". You will see some icons including Telegram icon that has a link as

An official account should show (not hide) the telegram username (handle), not hide like what is shown in the screenshot. Scammers can impersonate official accounts by hiding Telegram usernames (handles) but copying and pasting an official username into Bio area on scam Telegram accounts.
