Add all free items (packs) to your account!

i think you can remove demo - i haven't tried yet but it says hide demo

I don't want to demonize this method, but it should be used with caution.
I tried the steamdb method to add free items. You got a lot of unwanted stuff installed with it. There are filters, thats correct, but you install a lot of crap games, many with unreadable characters and a lot of Prologe titles and other 🤪.
Prologe titels are not filtered by the DEMO filter.
So, if you want a try by this install method, it is better to test this with a Steam test account because it cost a lot of time to remove undwanted stuff from your library.
If you need to remove items from your library, here it is:

As OP has said, Valve has recently removed the 50/hr rate limit for free activations. xPaw updated the SteamDB freepackage script accordingly. Now you can activate all free packages in like an hour instead of two weeks of continuous effort, if you wanted to clutter up your library.

Remains to be seen whether this is an intentional/permanent change or Valve making a mistake that will be fixed with Tuesday maintenance.

i saw that sadly
