Have my own instance running and took a look at the database myself, figure i could answer some of your questions regarding to Lemmy in general. Lemmy doesn't collection user's ip address, unlike reddit. There is no user behavior tracking as of now, and i don't see any third parties data collection based on my knowledge. User passwords are encrypted with Bcrypt which is one way encryption with no known weakness so far, the value in database is irreversible. This is standard practice. Basically admin has no way to know your password. The private message is not secured as Lemmy would warn you. Lemmy encourage server to use third part secure message service.
Computershare removed my PLAN 0.0 completely

I asked them to remove this 0 plan from my account because it made me uncomfortable, they told me it's fine but I insist, so the clerk created a work order to remove it from my account. I got the work order number but then forgot about it because the clerk also said it's not guaranteed.
Today I login to my account,
