So i notice on tengaged that a lot of players have the motif on their profile that says they are against animal cruelty. Good, you should be.
However, a lobster is an animal. It has been proven that it can sense fear and will actively try to avoid it. Therefore it is not in any way funny or not cruel to put one in to bubble bath and laugh hysterically when it then dies. Even worse to film it and post it on the internet as some hilarious kind of joke.
I remember Guillomouve doing just that. Torturing a lobster to death.
