Alright chat this is where I'm at.
These screenshots prove the 17 y/o and 19 y/o are in a relationship. I don't care about it unless information comes out the relationship is toxic or abusive. While it can be strange for have an adult and minor dating a 2 year gap isn't overtly concerning to me. The maturity of a 17 y/o can be high and/or the maturity for a 19 y/o can be lower bridging the gap of 2 years, that is literally how any relationship gap works even in 6 month gaps; its just how people grow and progress. Unless there is any evidence the relationship is bad I will leave this as is now.
Update as I wrote that last part sevral hours ago. There was also and announcement in server I'm posting below with more info reinforcing that I don't think this situation is a problem.
Now VinVan. I'm not delving into Shipcourse any further. I will lay out that Vin posts NSFW art of him and his "yumeships" in his server. The context of them are often of him and adults (ie. Dracula) sometimes either partly in little to no clothing. (Ie. Dracula nakid only covered by a snake or Vin himself in only underwear and a shirt) He also posts art of him being abused in a sexual context. (ie. Being whipped and medical malpractice) If you're in agreement with this type of shipcourse and his posting of it to his very large and mostly young audience be that way but i will say I am strongly against this. My opinion is he is sexualing himself to the adults in the server and normalizing that to the minors in the server and putting everyone at risk, especially with how large his server is with over 39,000 members.
I will not be sharing these images here as they can be very disturbing and I'm not comfortable saving or posting them anywhere; they are available in his server if you feel you want to confirm what I'm explaining here.
This is my final piece on both topics for the foreseeable future
