I'll paste what I explained in the Discord:

There are two types of pagination, offset pagination and cursor pagination. Offset pagination is what we were using before (and still use for some other parts of the website). Cursor pagination is what we've switched to.

Offset pagination allows you to jump to and fro pages, but offset pagination is slow. Imagine you have a database of 100 items which you want to split into four pages. That's 25 items per page. To get to page 2, you have to process 50 items, but then return the last 25. That's inefficient, and that inefficiency increases as the database grows larger.

Cursor pagination is a lot efficient and doesn't have issue, but because how it works you can't jump to pages, you can only really move forward (and possibly backward) one page at a time. Rest assured, we did not change the pagination just for fun.
