Is this acceptable fluthering?

There was recently a question posted “Who wants to have some sex?”.

The first comment was from dynamicduo stating that he had some this morning and it was quick.

My question is, is it acceptable to sarcastically, poke fun of people on fluther that you don’t really know or have had few discussions with (with only the intention of being funny and witty)? My initial instinct was to make some sort of sarcastic comment towards the answer but I wasn’t sure how it would be received. Obviously out in the real world you need to be cautious about pissing people off, and having fun at their expense, but I feel like here at fluther even though I don’t personally know any of you and have had long discussions with only a few of you, that it’s more of a friendly atmosphere where people wouldn’t get pissed at quick little jabs? Am I right or do I need to curb my initial thoughts and not take sarcastic jabs at people?
