Okay I say this not because you should hop on the next scam trend, but I meant this just in general, so you don't have regrets not joining even if it's just an invite to an online community, just like I did. I recall back to when someone talked to me in an Anime forum (my first), and they invited me to their Discord channel. I said I don't use my account often, and that was the last I heard of them. Now I live in regret for not even trying and maybe leaving if I didn't like it.
Oh well, there's always next time...?
