This is what i like about roobet and they are actively giving away so many promotions on the Twitter and you only need to be active there or on this thread and you will be updated with the latest giveaway.I think there will be soon one art contest back for the members to come up with new exciting arts for Mr.Roo 
Although I participated in all of them and never won any prizes, I can't wait for the upcoming one. It's always nice to see other people's art, and and there's always a couple of really good works there.
the safest way would probably use a system where data is stored briefly in a cryptographic way and deleted after verification
but I bet most of the websites store it indefinitely.
The regulations I know about KYC (and which are valid in the EU, for example) require exactly that, yes. Companies like Roobet are not allowed to do the checks themselves, but KYC is done by an external and certified company. However, since Roobet is not based in the EU, I do not know if this also applies here. but I bet most of the websites store it indefinitely.
But the main thing is: the data would have to be deleted immediately after the review and may not be kept. Whether anyone adheres to this is of course another question ...
yes, this is the thing
it'd be easy to do, but probably there are shady companies that don't do it

Probably there are such companies, but they are surely not among those a site of the level of Roobet would cooperate with.
