“lol” as a punctuation mark

Is there anything worse in the world of online-authorship than using “lol” as a type of punctuation?

I give you the following:

hi, i am from houston, texas. i am on here to see if there are even any singles in the church in texas. im starting to think not lol… trying this out for either friends or for other… whatever happens lol…

It’s like… it’s like “lol” means “said sarcastically” or something. It’s not THAT hard to convey sarcasm in writing, is it? How about trusting the reader somewhat, how about that?

I think I’ll kill everyone who I find using it lol
