Your ratings should speak for themselves, so titles like that would be pretty redundant. Also, I'd imagine that such a system would create more incentive for cheaters to cheat.
Chess.com titles
There is also the issue that ratings don't always reflect ability.
In my case I play on two chess sites. On this one I don't care what my rating is; I'm here mainly to learn from the chess videos.

Ok mayb cheating wud b an issue.ok cheatin is harder in live blitz.or they cud put stiffer penalties.sum piple r jus dying 2 get a title b4 they die..or sumthan.

The whole point of titles is to show over-the-board ability, the ratings in place already show online performance

Even if a chess.com title system were to be implemented, I don't think achieving such a title will provide the type of prestige that you're striving for. After all, people often say here that online ratings mean nothing. The same could be said of online titles.
If you're so desperate for a title, you might as well try to get one in otb tournaments. Is it hard to find FIDE tournaments where you live?

Actualy yes.i live in a remote country.and fide doesnt care about africa.chess.com titles wud b prestigious in my eyes.imagine changu chess.com gm!or kens mum gm.they cud do it in da blitz 1st.and whoeva said online is jus ratings not titles.we cud change things.thats why we here.CUM ON CHESS.COM STAFF,U HEAR ME!!!
My suggestions for chess.com titles:
below 1000: MM = muppet master
1000 to 1500: GM = gonzo master
1500 to 1800: KM = kermit master
1800 to 2000: FM = fozzie master
2000 to 2200: WM = waldorf master
2200 to 2500: SM = scooter master
2500 to 2800: LMPM = little miss piggy master

Wat?no,u wil ruin everythan.stick to M, CM,IM,GM AND SGM.we gatta force this down their throats.i nid a million followers and wil write a note.oh female titles,so kensmum u cud b WGM or sumthan close.

No thanks, I'll pass on that :)
You should probably post this on the "Site Feedback and Suggestions" section. That would seem like a better place to promote this idea to the chess.com staff.

Kens mum,wat u mean no.u cant sei no!if u gud enuf,we shal crown u by force and title u as Wgm,or wateva.mayb jus master.yeah,wil do dat.but i nid 2 c wats the general outcry.yeah so anyway.
