Right. If it is a set up, I'm sure you're part of it since you're posting the same thing you've posted in the other 72 posts. *grins*
Roleplaying with people who don't roleplay can be hard. Impossible even. That's at the base of what this person was saying. If you're fine with having your character finding people that say strange stuff like lmao and rofl, fine. If you think we should have roleplayed in Molecular Blue like we were all miners that picked rubies, emeralds and diamonds that sprung from the floor, fine too, I guess. Just don't expect it to be seen as common sense though.
I agree that players can roleplay, to a level, even without a good quality participation from others. You can take advantage of what is around you and drop it into your own context. However it is normal that people request better interaction from other players, and a better approach to what they think is roleplay.
I know this discussion sounds repetitive, but some people can't use search. And that's what I believe you should tell them if you're really annoyed by these. Not perpetuating a conversation you deem as pointless and recurrent.
