How?

hover over post title, you will see 3 dots

Can't hover on mobile

click on right top corner then, but i guess it may be bugged on mobile, will check if it works

I can only hide OP, not hide or delete posts. Of course it's bugged this site is trash

it doesnt recognize your account, probably you cleared browser storage or something ideally you should upgrade your account to permanent one so system can identify threads you own.

(click on 3 dots at top bar)

No. Fix your garbage site

it leaves identifier in your local storage so it can track whatever posts you made so you can delete them. you made op post from either different browser or you deleted sites browser data after making it, so it cant recognize you as the owner of the post.

you sure if you even understand a concept of datamining?

I can't even delete or hide tge posts i'm making right now you idiot, it has nothing to do with clearing data but all to do with your low quality pajeet code

well then there are either one of 2:

1) you dont have local storage enabled for this site

2) you using some 3rd world phone with outdated browser

Cope, localstorage is enabled for every site by default and i have the latest version of Chrome. Fix your shit code

but it works great for me on mobile and every modern browser, im not sure what the issue, probably 3rd world hardware or something.

Oh sorry, im just a cocksucker who wants some attention because my mommy didnt loved me.
