If you mean, does it delete your data... Not exactly. IIRC when you delete your account it disassociates your comments and your screen name (e.g. your comments remain but it shows as [deleted]
instead of your s/n). But doesn't actually "delete" your data. What I mean is that in their databases, likely they still retain your email address/screen name/ip address/browsing history/etc, even if you take the time to delete comments and posts before you delete the account.
But more importantly, I don't believe that OP is entirely correct (last line is wrong) either. Doing this just requests a report on what data they have about you. It does not say anywhere that they will get rid of the data. As to whether or not you can request the report after deleting your account... I have no idea. Possibly but I would imagine they would make the excuse to say they can't though.
Haven't been back there and didn't read the comments...
But I think I can understand to a degree:
I think there are a lot of advantages they're probably missing too. I like that kbin/lemmy we can choose whatever fucking avatar we want instead of being limited to customizing our snoz or wtf Reddit calls their mascot thing. I saw one guy mentioning how there's no karma bullshit to deal with for new accounts and absolutely agree with that sentiment.
tealdeer; meh, I like the fediverse and it's not hard for me but I'm not shitting on people who don't get it. If they want help, would probably help but not going to push it on people either. It is what it is and that's good enough for me
