Websites who sell games

[Char]

I tried to have informations about all the websites who sell Games and especially those who sell steam keys , i found this reddit post : https://www.reddit.com/r/Steam/comments/2yhnsw/key_resellers_and_what_they_mean_for_you/ , there is a list of website selling games that are legal , at least this is what this post say . So , i want to ask on steam ( especially if they are persons working for steam ) if , when we buy steam keys on these following websites , we can get our keys cancelled or , even worse , or steam account blocked or banned :
- https://www.bundlestars.com/en/
- http://www.desura.com/ ( even if they are also numbers of non-steam games on this one )
- http://www.gamersgate.com/
- https://uk.gamesplanet.com/
- https://groupees.com/
- https://www.humblebundle.com/store
- https://www.indiegala.com/
- https://indiegamestand.com/

Thank you for those who will answer and have fun playing games guys :D
