Whenever I see people with big sub numbers fishing for subs like that I immediately think "This person doesn't care about me personally or the community they're gathering, they literally just want anyone that'll join and they'll immediately forget about me because I'm not much more than a number to them". It feels like getting used. And when you have a channel of your own and someone starts giving you praise, saying your stuff is great just to get views on their own channel, it honestly hurts. At least to me. I'm doing the best with what I got and instead of even looking at the video they just click, pause, spam, and run.
There was someone who did that a few days ago, throwing all this praise at me about how amazing my work is, then asks me to just go and sub to him. Not watch his videos, just sub. I didn't reply to the sub part, but I did my usual "thanks hope you enjoy the rest of our work, and I hope you consider subbing and liking the videos if you enjoy them". He just comes back and says "Please go and sub to my channel". When I told him no, and why, and asked why he wouldn't sub to me if he loved it so much he gave me some spiel about "looking for consistency" and "I just wanted to give some encouraging words, it doesn't matter if I didn't watch it". After I told him what I thought of how he was treating people by just flattering people to beg them for subs he left dislikes with two separate accounts on that video and a dislike on the one before that. Petty nonsense.
