Is it bad that I giveaway my own wishlist?

No, as long as you activate the games when you win them. :) Many people here give away games from their wishlist, including me.

Nah, as long as you activate your wins on your own account, you can give away whatever you want.
Sometimes I'll win a game, then buy a bundle with the game in it a few days later, and give it away.

No big deal. :)

When you win the game, you must activate it, thus making it disappear from your wishlist
Giving away wishlisted game means that you haven't owned it, so it is not violating any rule.
It just that some new members who don't understand the system here, make giveaway of their wishlisted AAA game and hope that they win that game lol

I've also given away 1 of my wishlisted game, and someone with name similar to you won it.

I see many people doing that :). I've done that too - I'm giving away "Child of Light" and in the meantime (while the GA was active) I also won this game XD. And I've done it few times before. There's nothing wrong with that. You can always check if the person activated their wins, many times it may not be re-gifting, but someone simply enjoyed the game and bought it again to do GA.

Yeah, it's fine. It can be infuriating to see your own GA in the wishlist section though and not be able to enter it.

Done it before and I'll probably do it again. I like to infect other peep's wishlists with the random crap I find :P.

If you install SG++, user profiles have direct links to their SGTools Non-Activation/Multi-Win pages, which wouldn't show any sort of issue for what you're describing.

In other words, for anyone that actually cares to put in the time to check regifting, the number that won't have the patience and resources to spend an extra 10 seconds to also check it properly are going to theoretically be a very small subset.

And no, clearly you'd give away games you've enjoyed or expect to enjoy.
Why would you give away games you can't stand [bundle leftovers aside]?
I don't understand the premise to this concept, or why anyone would default to a regifting assumption over it :P

What is a wishlist? How to put a game on my wishlist on SG?

I've seen it many times done here and I have done it before and will do it again.

I thought like you at first that it could be seen as a false positive but in the end if you win just activate and mark received and you're good.

is it?
was event about it twice at least :)
