I will invite people to lobste.rs. Because of their rules (you misbehave, I have to bear the consequences) I will not just invite anyone, but only people I can find on the net and can be reasonable sure are not assholes.
So write me a mail with some information about yourself (have a look at my profile for the address) and if you don't look like a total dick I'll send you an invite.
I do have three keybase.io invites as well.
