I’d make Fiverr FAQ it’s own top level category and have it be an actual FAQ, a read only section, with all the FAQs and answers of the simple Q/A kind, like can I have 2 accounts on different devices, that are being asked over and over again and clutter up random other categories.
Mods could move “topics” that clearly are answered by the FAQ to the relevant FAQ, in a locked state, then the people asking could read that FAQ instead of other people having to repeat themselves ad infinitum.
The FAQ could also contain "themed collections of topics about not-so-clear-Q/As in form of a list of links, like “How to make my first sale?”. Mods could curate those FAQs, and make updates if anything “official” changes, like ToS, add new relevant threads to the link lists, etc.
Like that, such questions could still be actively discussed on demand in the newer threads that would pop up in the “last posts” lists and their original category, as there can always be new people, new angles, new developments, etc., but the people actively looking for a “best of” to their question, could find it in the FAQ (and check out the linked threads for more, if it’s no simple cookie cutter FAQ).
I’d take “My Fiverr Gigs” out of “Your Fiverr Experience”, it doesn’t really belong there, IMO, and call it “THE one place to advertise your Gigs” or something.

I’d drop the top level (a top level category for only 2 sub categories seems to complicate the whole category system rather than simplify it) and make both of these top level + try with “from” instead of “for”:

I’d add a “Forum Fun” category to Your Fiverr Experience, for things that aren’t really conversations, like the fun emoji threads and whatever people else might feel inspired to come up with at the sight of such a category. (Maybe some threads that probably would get much resonance like “You know you’ve been on Fiverr for too long when …” kind of fun threads could be pinned as “forum staples” that many people would enjoy and add to)
Perhaps move the “Weekly Polls” away from “Events” (would anyone look for a poll in “Events”? Not me., maybe also remove the “Weekly” (are they really weekly? I don’t notice them coming up in the newest topics list as often) and perhaps make it a category for all forum users to post polls in instead to make it more lively?
