Does the 3-day limit apply to game gifts purchased directly using Steam Wallet?

I am asking because I am planning to do a test using the "gift" feature on this site and I don't want to be suspended for something I didn't know.

The 3-day limit I am thinking about is the required days to be friends with someone.

What 3 day limit are you talking about?

I've recently received gift cards from two different people and was restricted from using the community market for 3 days afterwards each time. However, I also recently gifted a game from Steam directly to somebody on this site, whom I had to add in order to gift them the game. I was able to do that instantly and no restrictions whatsoever occured afterwards or during the gifting process.

As others have said, you can friend someone and gift them straight away - there are no restrictions. Except if you do this often, Steam might decide you are a trader and block your account from gifting.

I go with the 10% rule. Tho I believe I was able to gift a 12% once.

My "testing" involves adding SG winners as Friends on Steam. I then use the Steam nickname label to identify what country they are in.
I can then go to the store and gift the game without ticking the accept box for actual purchase. Do dry runs on the more expensive countries.

It will deny me and wont let me agree to purchase if I cant gift to that region.

I need to pick up Israel and Swiss Steam friends as those are usually the most expensive.
