special spellings

[WMX]

I've seen x for por aki for aqui and kiero for quiero etc. How common are these spellings and are they acceptable?

[sosia]

they are SMS (phone message) spelling. Also valid for internet chat.
Not acceptable in any other place.

Another one I've seen is to2 (to-dos) instead of todos.

Muchas gracias a los 2.

Is this the equivalent of english 1337 (elite) talk or is it actually commonly used?

[Tomisimo]

I think leetspeak came out of the gaming community and is somewhat different from the sort of abbreviated words used for texting.
