I am a little autistic about my library of games and I am ashamed of some of the titles that I bought. These games turned out to be complete shit and I don't want to see them in my library.

Unfortunately, the HIDE function does not sync between the online list and gog galaxy, so I would like to completely remove a number of purchased games. How should I do it? Do I really have to write to support every time?

You really hav to write to support. And also good luck with it, in the last two years depending on who answered the ticket they either removed games or said that it is not possible and nothing happened.

I'd ask them to move your copy of huniepop into my library if I didn't have it already :<

Seriously, is this a problem?

How often do you watch your GOG library and feel ashamed of it?

There's crappy free games that people don't want taking up space plus they might no longer want demos there too.

Keep them to remind you to not buy any more crappy games.

Don't use Galaxy anymore. Only offline installers. Problem solved.

I had fun playing Huniepop, should I be ashamed ? :p

Yes you'll have to ask support as it's not something you normally do.

There's no hurting having the games. There's games i bought that are utter crap it seems and only after getting into them that it's obvious. Like Raving Rabbits...

So i suggest just marking them 'hidden' and they won't show up unless you explicitly open the hidden drawer. Like throwing the games you dislike under the bus... or bed... or whatever.. Yeah they might come back as the uner-the-bed-boogy-monster-games but it's not that bad, it's not like you HAVE to install or play them.

Don't be in denial about a part of yourself.
You can't erase what happened, so embrace it.
