dont allow shouts or tells till lvl 20

It's pathetic how minor it is in comparison to filling up your Blacklist weekly with RMT shouts/tells in yet people will still find fault.

I've never filled my blist, and adding people to my blist takes two clicks. /s would usually take me at least 4, /p 3 assuming I'm not already in a party (like, say, waiting for PF to fill), /l would involve starting an ls dedicated to conversing with lowbies and would also require at least 3 clicks. So, yes, each alternative you've listed is actually more involved than adding someone to my blist, nevermind that it needlessly alienates new players.
