I mean, you/me cannot assume people with 2018-2020 CC join dates have only been on Wikia/Fandom that long- that is just when they made their first appearance to CC. And if they do not list their top Wikis you can't stalk an account to see their Activity.

For some or maybe even many- they only came to CC since UCP announcement/migration so we really do not know if they have been with Wikia/Fandom for 1-2 years or 5-10years unless they say.

That is why I was careful to say "they seem to be new users".
