First of all, I and my friends _do_ say lol, and not laugh. IRL. But that does not matter here.
What I tried to say if that is obviously enough OOC, like taking screenshots or such, there is no need to mark OOC with brackets. Of course you need to mark it when starting OOC-revolutions, but that's not the case in the screenshot that was complained about, right?
In my opinion, saying lol is no different than saying ::laughs out loud:: or whatever the current trend for marking actions is.
