This is a weird request I know but some times when I want to post sales of games to other sites using GG deals so people are "aware" of how easy GG deals is to compare shop prices.
The sites get angry keyshops are listed.
So if there was a URL way to "hide" keyshops
For example something like ; https://gg.deals/game/dawn-of-man=&NKS
Or what ever like =&NKS - means do not display keyshop.
That would make it more welcoming by other sites - even if it means the person visiting can just manually activate it after clicking it.
