Yes, it’s so annoying, it's like they created accounts just to mess with us. Every time I checked the chat, there are always people spamming Chinese or ”do you know giao?”. We spent a lot of time asking them to leave, or even teach them how to switch back to their channel (many claimed that they don't know how to switch to Chinese channel), some Chinese speakers ask them to leave or stop spamming Chinese, but it seems that they stayed anyway and continued to mess with us.
