Talking to avoid scam telegram groups, but you offered anyone to join your groups since you claimed it's legit group.
Yes, we should avoid all groups including you.
Well, we will only know if those are scam groups once we start participating in their telegram groups. But if we manage to be knowledgeable and smart all the time, as long as there are red flags in it, then its a sign not to indulge ourselves. However, useful tools and channels did exist, but the problem is we find it hard to determine which are useful and which are not.
