It really depends on the context... if every time you are sharing something you are not repeating yourself in almost any aspect, then that's just normal "frequent" posting, but if the thing you are doing is constantly being the same, and it clearly shows that someone is just reacting and not thinking... it becomes a bit problematic, especially when there is no real intentions of causing any harm, but as a result, things will be seen that way.

Posting is after all the most freedom related way for people to communicate on chain... :D but with power, responsibility it comes :D

I just wanted to be clear that this should not be an exercise of blocking things that we don't see being very good to the chain necessarily (because there are other consequences of doing that), but instead an educational theme, in order for people to embrace the wider perspective and responsible way.
