I would like to sell my Uplay or steam game accounts and keys. According to rules, can I do that without getting my gigs deleted?
Contacting CS will be the best option for you.
But in general, if the game company doesn’t allow selling accounts, fiverr will/may delete your gig.
Cs will most likely tell you to check the third party terms but as it seems your dont want to do it yourself, you can make a buyer request and get someone else to read uplay’s and steam’s terms to see if its ok.
That would be a violation of Uplay/Steam Terms of Service, and therefore, a violation of Fiverr’s ToS, too.
You could get your gigs deleted, or even your account suspended, considering that you have also copied the tagline of a TRS.
Fiverr doesn’t allow gigs that are against third-parties’ terms of service. So even if it’s okay with Fiverr’s ToS, if the game in question doesn’t allow the sale and transfer of accounts - you’re shoot out of luck.
