My man fillippone, if that's the first (or even second) time you've been annoyed with a forum member in 8 years or so, you must be a Zen master. I think it took me about 5 minutes after registering before someone here went well beyond being an annoyance, and that was a decade ago.
You're more than justified in being pissed off at that jackass. And the only other thing I want to say here is that telegram sucks; I set up an account a long time ago and the first thing they ask you for is your phone number. For anything crypto-related, that's a no-no and I don't care how much you can adjust your settings. If an app/platform/whatever is going so far as to need that information, then that's their game: they want all the info on you that they can get, plus it's a privacy nightmare. So props to you for calling this moron out and fuck telegram and all the other social media data vacuum cleaners out there.
Well, I usually gave benefit of doubt to my other locals as well. But things are changing. It seems some people never learn. I recently noticed the spike in activity in our local thread. I am certain that not all of them are pure newbies. Some of them had other accounts on the forum which was either for bounty hunting, or they got their account red painted by DT members.
No doubt that's not specific to your local board--using alt accounts to evade bans and to cheat sig campaigns/bounties has been widespread for years and that problem comes from all corners of the globe.
