Is there a way to blacklist games/dlcs here in SteamGifts ?

there's a button with crossed eye near the giveaway. You can press it and then add it to blacklist

without entering:
Hide All Giveaways Button

If you look closely near the title of a giveaway on the main page, there are two icons next to it, one of which shows an eye with a line across - clicking that icon will add the game to the blocked list.

Woow thanks guys, to be honest i never knew about this eye icon before lmao
