Drop times are different after you refund a game compared to before you've ever refunded a game.

With an old account the 1st card can drop after 5 minutes. But if you refund any game then the 1st drop for a game is then after 2 or 3 hours.

Do you have fast mode on?

Does you badge page say 1+ "card drops remaining" for all of the whitelisted games?

Or if you have augmented steam then the browser store page for the game will say how many card drops left you have.

Oh my, didnt know about that refund thing. Yeah i have refunded a few games in the past.

Does this affect also them other games?

As i said, i am running "whitelist mode". From what i understood, it cant be combined with "fast mode". Or can be?

And yes, all of them games included in whitelist has actual drops remaining...

Ah, just checked unfortunately whitelist and fast modes are mutually exclusive. So card drops will be slow I guess, I've never used whitelist mode so I don't know how it works with regards to idling games simultaneously.

So should i do it the other way - putting the games which i dont want to be used by IME on blacklist then starting it in fast mode?

Up to you, it could be a lot faster if whitelist mode isn't idling the games at the same time.

Well ok... Thanks for your advices. :)

Uhm, do you have any experience with blacklist mode? I just spent alot of time adding these "App IDs" to blacklist. But it still seems like its not working properly... :/

EDIT: My bad! It was indeed working properly, there was just a huge gap in between of dem IDs bcs of poor Steam badge filtering.

Everything is OK and fast now! :)

Conclusion: Its better using blacklist than whitelist, thats for sure...
