Set `noprocrast` in your profile to `yes`.

I had to look it up. very fun.

There are three new fields in your profile, noprocrast, maxvisit, and minaway. (You can edit your profile by clicking on your username.) Noprocrast is turned off by default. If you turn it on by setting it to "yes," you'll only be allowed to visit the site for maxvisit minutes at a time, with gaps of minaway minutes in between. The defaults are 20 and 180, which would let you view the site for 20 minutes at a time, and then not allow you back in for 3 hours. You can override noprocrast if you want, in which case your visit clock starts over at zero.

Same, mostly, other than the fediverse. Anything with ads and targeted marketing is more the problem, imo.

I tried to look for a way to delete my account yesterday but I did not find such a thing :<
