Yeah, nice spam.
Taiwanese travel agencies have been offering visas to Mainland China for reasonable prices for years. And one does not need to travel to Hong Kong to apply. So not only is your post spammy, it is also factually incorrect.
For anyone interested in reasonably prices visas to China, just check out any of the legally established and registered travel agencies in Taiwan. Prices start at around 2,500 NT$ for a single entry visa to China.
