I did have more than enough profiles to create and improve in the first year I was on wikitree, but now that most of my tree is on Wikitree, there is not much else for me to do. And As I said before, I cannot do much in the way of Notable profiles - unless they have died.
I personally do find the GDPR restrictive in that I can no longer start up a Notable living person, but I know I cannot do anything about that - for now.
The last 1000 badge I received was in March 2018 - but the one before that was way back in July 2017.
I never have any trouble getting the 100 badge every month. In fact, right now, I am sitting on 99 contributions exactly. LOL
