Great question! I think the goal here is to clarify what is and isn't lashon hara. The thing with l'toeles is that it would depend on the listener/reader, which is quite hard to handle on a public forum. I've been wondering about this for a while.
I don't think so.
For example, we said specific examples can be given l'toeles, but using words can be exaggerating, and shouldn't be done.
For example:
Plain and simple, the amount of lashon hara on here about restaurants is
astounding. The
horrible language
Is that allowed, even according to what you are saying? Or are those the modifiers the OP and the ensuing conversation is specifically calling out?
