Probably the stupidest thing about all of this (well, aside from the fact that dumbshit fuckwits are able to be """""funny""""" and add inappropriate tags in the first place, of course) is the fact that when you flag the bad tags as inappropriate, those tags will continue to show up on the main store page for the game in question and will show the tooltip "You applied this tag" when you mouse over them. This is the case even after the flagged tags may have been properly removed altogether if you look at the expanded view of tags. It's like, no, you stupid motherfuckers, I did not "apply" those tags, I flagged them to be removed because they were wrongly applied by others.

The only way that I've found to make the flagged tags no longer show up as "You applied this tag" on the main store page for a game is to go into the expanded tag view, then explicitly apply the tags that you'd previously flagged as wrong, and then immediately remove that application of them. Only after that do those tags no longer show up on the store page as applied by you. Of course, you can't actually do that if you want the tags to remain flagged as inappropriate if they are still there, because doing the above removes the flag as well. It is utterly boneheaded, and obviously a bug that Steam needs to fix (one which I reported to them years ago, but as has been shown to be the case numerous times by this point, Steam customer/technical support is... subpar, even at the best of times, and this certainly isn't a "best of times" case).
