I think the best we did was the invite giveaway on /r/redditalternatives. Doing any advertising outside that area that's specifically meant for advertising alternatives would probably be frowned upon. I guess if a user mentions they're looking for another place we could reply with a Snapzu invite, but I wouldn't bring the issue up. But I'd definitely check the subs where Redditors are dissenting and revolting.
EDIT: Also, keep a look out for people wanting to join but need an invite.

I'm fairly sure OP meant to share only if someone is asking about an alternative, not just randomly. But I understand your concerns for sure.
