What about Image-only meme threads that are there just for the laughs?
I've seen whole threads like that go down the drain, either by a lock or by a removal, while the thread virtually harmed nobody nor the rules.
I can't speak for other Mods conducting past actions, nor will I discuss such actions publicly, if it were me doing it, I'd take action in such a case if things were going off the rails with regards to violating the community guidelines. Topics such as "The user above me is a..." Tread a fine line.
It shouldn't be a problem now as long as there is a single thread and it stays civil. The only reason the thread in off topic might have gotten locked is due to kids going overboard. It's good we have chilled out mods that judge if things can pass even if it breaks the rule. That's what separates a good forum from a bad. When mods are too uptight,there is always a problem. When they keep the forum in check but with a lose hand, I think that's the perfect balance.
So from what I understand, meme only posts are allowed as long as it doesn't go overboard or take away from the topic.
Essentially. If the conversation is serious and productive, Don't derail it with pointless, trolling, meme responses, we won't have a problem.
Typically it's best to err on the side of caution outside of the Off-Topic forum when it comes to such things, we'd appreciate it.
