I was also a big fan of Seb's channel and subscribed to his Patreon. His livestreams were a lot of fun, and there was a lot of interaction from him, inside jokes etc. I was (actually, still am) part of a groupchat with other subscribers and we invited Seb to be part of it during one of the livestreams, which he accepted.
We had a lot of great banter and even a few deeper chats with him over several months. He was surprisingly vulnerable and told us a few personal things. He told us his full name when few others knew it. He shared selfies. He got to know us. During the subsequent livestreams we would chat privately at the same time and it was all very fun and felt like an "insider's club" of sorts.
I will say, he never defined his sexuality in any clear terms but insinuated that he preferred to remain "unlabelled" which we all supported, telling him he should not feel obliged to label himself purely to satisfy the curiosity of others. He often expressed physical attraction to male celebrities including, of course, Chris Evans, which has become the biggest running gag of his content.
An ex-girlfriend of Seb's contacted the groupchat and shared some screenshots of arguments with him to try and warn us off him, however i admit that myself and the others were too wrapped up in our friendship with him at that point to take it seriously, despite the behaviour he displayed in these screenshots being a major red flag. We all agreed that relationships are messy and it was none of our business anyway. We forgot about it and moved on.
There was, and still is, a lot of commenting and speculation around his sexuality, and i suspect this is one of the reasons he no longer really does livestreams. Also, some may remember he discovered LPSG after googling his name during a stream and was visibly, somewhat understandably, upset over the posts about him. He seemed to take the queerbaiting accusations as a real blow, and was uncomfortable with some of the attention. We reassured him he shouldn't take it too much to heart, although i think this is when he started putting his guard up and interacted less and less on social media.
Around the time of his Dubai holiday last year, something seemed to change in him and he stopped communicating with the groupchat quite suddenly. He effectively ghosted us for weeks and then abruptly left that chat with no explanation. In one of his Patreon posts he stated he no longer wanted to pay attention to too many "opinions" or be influenced too much by social media. It seemed a bit of an odd left-turn after him being so open and interacting so much.
Eventually, myself and the others took the rose tinted glasses off and realised he'd actually acted pretty terribly towards us after initiating what seemed to be genuine friendship and even suggesting meet-ups, to then cutting off all contact. We also started to see how overly confident (and kind of annoying) he had become, and his content also seemed to be getting worse. As others have said, the reaction videos have become an excuse for him to shout "ayoo" and mention Chris Evans at every opportunity, and he does seem to play into queer men's attraction to him for monetary gain (for example, keeping a lot of LGBT content as Patreon exclusives).
Anyway, we all unsubbed from his YT and Patreon. Looking back, i think we were very much blinkered by our fascination with him for some time, and while i don't think he's the worst person in the world, i do think he's somewhat immature and has personal issues he needs to work on, not least of which being the way he treats other people.
Regardless, i made some great friends out of the situation and we met up irl and had a great time, so all good
Also, if you're reading this, hello Seb lol.
