Like, I’m probably answering myself here but I think it is pointed out by gatekeepers who can’t stand the idea of community growth and everything should adhere to some other unfound arbitrary way to keep things ‘pure’ in a community.
When they forget that they too, started out as new and that they too probably have had other people sneer at them for simply being new. So now they go around and pretend this is some kind of ultimate shut-down insult to people who’re just trying to contribute to the fediverse by devaluing it by saying “OH U JUST SOME DAY OLD ACCOUNT, NOBODY SHOULD MIND THEM!”.
You mentioned in a comment that you have another account. So you aren’t new here, your account is. Not sure why you’re pretending to be new? This is what gives people trust issues.
Also- your comment history isn’t hard to check. No one has said anything to you about being new… unless you’re talking about another new account you have?
