He might be an alt account of this dongqudalaoli who promoting with Canaan official website that includes a fake telegram link.
Canaan never use telegram to contact their customers. So there is a big possibility that this man is one person trying to promote something or the telegram link.
I believe sooner or later if this thread is already buried in a few pages in this section he will edit his post and add the telegram link just like other users who try to manipulate the forum.
