How to deal with text speak in a question (or answer)?

To what extent should we police text speak? I have just read a question whose content is very valid and that is written in fluent English, but the style gives me a rash. Full of plz, cuz, ofc, ur, plus a good dosis of space-commas and other weird punctuations.

This is not pleasant to read. Yes, I could just ignore it. I was already writing a comment about this aspect but didn't want to look petty, giving more importance to rules than actual technical problems.

So, how would you react? Ignore such a thread, write a comment about ugly language, report it, privately message the OP, anything else?
