Watch for this behavior and you will see it often.
If a Lemmy user can call out the age of an account he or she will use that as a way to dismiss and degrade the post that he or she does not agree with.
Y’all would enjoy Lemmy a lot more if you just focused on the post and stopped feeling compelled to rummage through someone’s post history.
Sure, if that person has extreme political views, is a Nazi, or is astroturfing then maybe you have cause but clicking every single profile to find dirt to make an argument showcases your poor debate skills.

I spent the first 168 hours on Lemmy understanding it, finding communities I liked and getting the vibe of the place And within those hours I learned that accounts younger than mine with shower thoughts weeks of showers long, are most often not a building block of a community, but are rather intent on irritating, disrupting or just being way out there. Often actively being an unwelcomed part of it all.
Everything is always better when people act like people towards people. And you would never need to create extra accounts to communicate with people if you acted like a decent person towards others.
So more often than not, if you are new and you already know everything, you are a walking red flag that will have to prove you are not. Because if something is too good to be true, it most likely is.
