idk. I still accept it from others in text as non-ironic, usually. (A woman in her 30s literally just texted me "lololol" and I have to assume she thought what I said was funny). At some point though, I switched to "hah" or the more expressive "hahaha" as a way to avoid the lol-insincerity trap. That plus some emojis also helps obfuscate how old I am.
