Out of slots for blocking crappy game deveopers, any suggestions

You can ignore by genre, but it can be too broad depending on your taste.

Ignore by creator?
( Square Enix only used as Anachronox was installed and by hand)

no there is no way to block more curators. i guess you can change some shit in steam files or something to stop them from showing up but itll probly fuck with the weekly updates or whatever.

if one day steam allow people to add Personal\Useronly Tag , you then can just add an "ignore" tag and then use it as a filter,the problem is steam never do that until now,it's possible to apply tag but it's not personal and so if not become popular they can't be used as a filter\ignore hidden games ;(
i'm in the same your situation with the only difference that my problem is "Bundles\Packages" of games , hidden feature looks like not work for these ;( and i can't use the "genre" filter because if i try to check my steam library of games i like by put a genre that i want try to hidden\block then i see that a lot of games i liked become ignored too :( , top of this the fact that people make wrong\abuse use of not right tags in more games and make them be popular don't help too :(
for example i don't like walking simulators but i can't ignore that genere because i noticed that "Walking simulator" tag is also used in Rime,A Plague Tale innocence,Abzu,Assassin's Creed Origins and many other games that i like and that for me is not walking simulator but because others people apply it to them i can't use it :(
But this said my new release game pages on steam is 9.999.999 time better than the ps\xbox store,at least on steam i can hidden games i not own or ignored (if they is not bundles\packages)

Would be better if one day steam allow people to use personal tags that not need to be popular and that can be used with the filter,so that people for example can create a tag named "ignore",apply it to the bundle\package game him not want to see,and them use the - to the "ignore" tag in filter in this way then we can hidden all games we want,without need to care about who is publisher,dev,genre or whatever.
