Not-Interested-List in Steam gone

I'm sorry that I answer this late, but I had to leave my PC.

Thanks a lot for all the answers. Mine are back, too, now.

If you want to tag a lot of games as "not interested", this code will be very helpful:
tag all script

So, seems like the list is back again but I synced Steamgifts yesterday and that was a hassle but worked (didn't know I lost the list yet) and now the list is back so I want to sync again but it just doesn't go through, I need Steamgifts to know I ignored 10k games, any advice on that?

Wow, looks like some stuff went down, my list isn't gone but if it was maybe it went right by me haha.

Gaben knows well that people are just playing hard to get and wanted to prove this by deleting the lists so people will start buying the games they pretended to not want.
