Any_more (the correct use) as an adverb means "no longer".
In the context of your post it doesn't work.
The correct use would be:
"I don't read these posts any more."
"I don't care what they say any more"
etc.
You could say "I just ignore most of it now."
It's an odd using of "anymore". The first time I've seen it was on SSF... from Pliss... . Seems to be a thing for whatever reason.
