There are only three types of ads I post: 1/ I say it's an advertisement and then hold a lottery for everyone; 2/ I say you can buy, so I also buy; 3/ I seriously introduce VC coins, then no lottery and probably haven't bought either. Actually, many Memes ask me to advertise for them, with amounts possibly around five thousand to ten thousand dollars. Some have even paid (with additional conditions). If the amount is small, it probably won't be too low. But my condition is to clearly state that it's an advertisement. If I were a bit more unscrupulous, earning an extra ten thousand dollars a month from ads wouldn't be a big deal.
