Definitely NOT an ISP issue. I get this issue on my main computer, but not my laptop --- with both connected to the same twitch stream at the same time. (Watching a stream on my main desktop (hardwired) computer, got tired of the constant spam, so fired up the same stream on laptop -- no welcome spam there. Been happening on and off for a while now, usually only bothers me when I'm streaming, as I'm worried I miss viewer's chat.
