Last year, about a day before (or maybe it was a few hours before, I can’t remember) SCEA decisions were released, people on the Yale SCEA thread were all trying out the link that I posted above. Most people would see a 403 Forbidden message that said “This Portal is only for admitted students”, while a few people were able to see a message that said “Welcome to Class of 2020!” and other additional information. People were wondering if this was this was a leak, like it was a portal that admitted students are permitted access to once they get in; many ppl thought it could be a good sign but def not 100% sure. After the decisions came out, it turned out that the people who were able to access this portal early ended up being admitted, so it was probably legit.
