first of all. learn english. after ur second comma u put "could you invite to ur discord server?" which isnt an actual sentence therefore not needing a comma. fuckass. Also just join the dc, it works. (idk)

Don't let an obvious troll bother you. He doesn't open with capital letters. He put a period (rather than a comma) after "first of all".
Also, his comment is backward. Rather than not needing a comma because the question is "not an actual sentence", it should have been a period because the question part is a new sentence. Mixing up a period and a comma is something native speakers do all the time
