Is it worth requesting at this point, given my account being new? Just wanted to ask. Huge anime fan.

AnimeTorrents is open for registration!

Don't know about AnimeBytes, seems impossible

They oftenly open for application/interview on their website.
This is how I got mine.

Now invites are pretty rare.

Invites are rare because they disable 99% of invited accounts along with their inviters. If you are not from the same country with your inviter or real life friends (and be able to prove it) don't bother to look for an invite to get in.
Application or recruitment is your safest bet.

i wouldn't waste time on animebytes now that bakabt has removed the ban on licensed anime's. Just do the interview or wait for them to enable invites. I've used both bbt and ab and imo bakabt is much better.
