I didn't have a problem with his youtube personality. When I went to the breeders expo and saw him and some of his crew, they were quick to blow me off when I said I wasn't interested in retics, and I just enjoyed taking pictures. The animals at the expo looked fine. I wasn't planning on ever buying snakes from this guy tbh. Idk why, but I just got a weird vibe like they wanted my money and not my company lol. Most of the other vendors at the expos are so nice, and they enjoy chatting it up about the reptiles that they're selling because they love them! Brock, Heather, Maki, and several other forum folk are always so polite and fun to talk to!
Response to all the pictures: I've seen far worse in pet stores. Dirty substrate. Glass tanks that are so dirty on the sides that you have to constantly adjust to get a better look at the half dying reptiles hiding inside them... Dead crickets / worm. Mouth rot... This is all off the top of my head from a reptile store I visited briefly.
Those cages could use a quick cleaning.. They need to make sure they get all the flies out of there, and the water needs to be changed. I don't see any problems with the reptiles themselves in those photographs tbh. I won't just take your word for it, but I wouldn't be surprised really.
