Warn about games that are for +18 people

[MatterNoise]

According to the document "CommunityGuidelines.md"

It is important that all of our user generated content has no content that is only suitable for adults. If anything on TIC-80 you find looks too inappropriate for under 18s, please let us know.

There are supposedly some TIC-80 games that break this rule (especialy the mild-sexual sugestive ones) and are still present on the site, and yes, it could be argued that they are not as explicit, but they could still be considered unsuitable for minors, but if we were to simply delete those games, we would still lose the hours that the developers have dedicated to those games

That's why I wanted to talk about whether it would really be a good idea to put a warning (or simply make them less visible for non-registered users) so as not to delete the games but at the same time, not make them so visible for minors (I repeat, make them less visible, but not prevent them from seeing them), thanks for listening!
