They have that problem regularly, yes.
I'm regularly logged out after logging in and then the start screen reappears. If I click "enter the chatroom," I can continue; I'm logged in again. Strange, because they say they don't use cookies.
Usually after about 2 minutes I get logged out again.
And my photos are usually not accepted. I'm a cum pig, and in the photos I'm in my gear, jeans, hoodie, bomber jacket, and everything is covered in cum stains. It's probably too extreme for Bullchat. But when I see guys who are completely covered in shit, I wonder what their policy is then.
In short, it's a quirky chat app 😃
