Not going to defend the UI design here. Just wanted to add two small hints that may or may not be of any aid to you:
Regarding blocking tags: I find it's actually easiest to go to the Tags page, and look for any you want to block. Load up the page for each tag you want to block, and it will have an option to block the tag.
Also, you can try going to https://www.fakku.net/account/beta and switching Beta on or off depending on what it's set to for you. I find I like the non-beta layout much more. Just don't expect this to fix everything, search will still be kinda broken regardless of beta, and each of the UIs has its own issues.
Edit:
I just loaded up the
https://www.fakku.net/unlimited URL, and something does seem to have broken further than it usually is. It appears to be the Beta layout even though I'm not in Beta, and it also suggests I sign up for a trial despite being a member for
years.
The only reason I hadn't noticed before now is that I usually browse unlimted through
https://www.fakku.net/tags/unlimited, where I thankfully still have the non-Beta layout and I get all the works in chronological order with latest releases up top.
The default unlimited page used to at least have some categories with stories that could (in theory) have been selected by taking inspiration from your followed tags, giving both an ordered entry point, some useful suggestions, and some hints on how to use the search system to find more works of interest.
The current page.. is just one huge mess of titles with no rhyme or reason. I kinda hope it's just a bug that the page shows like I'm not subscribed or signed in, and the page looks much different once that bug is fixed.
