I really doubt an automated database dump is going to hurt them a whole lot. However, if you’re looking to eliminate everything you’ve ever posted (and I mean everything, not just the few recent posts you see on your profile), redact.dev (possibly others too) can use that zip to find all your posts and comments and edit/delete them.
Now I’m not saying you should delete your data. I know many people believe that leaving it there benefits humanity as a whole or whatever, but if you are going to do it that’s the only effective way.
Porkbun is awesome. A few months ago I transferred most of my domains from Namecheap to Porkbun and I’ll be transferring the rest soon.
Namecheap are still in my top 3 after Porkbun and Cloudflare though.
