Nope. They're just hiring a local agent of some sort. I wouldn't consider this spam.
It definitely is spam, created by a bot.
These bots also get nuked pretty quickly.
They do get nuked, but if this Boris spamming on a Chinese topic, why should it get nuked? The spam bots that spam in English topics should get nuked.
Spam is against the rule in all languages. Just because its in chinese and in the chinese section does not make it ok to spam. Not sure what your logic behind that is.
Its pretty obvious spam as its unrelated to crypto currencies, at least according to the translation and the translation of the site.
There are a few common topics for what is spammed here:
#1 nonsense
#2 educational related like the one in the OP
#3 grow your penis/muscle/etc. spam
#4 some other health nonsense
