@grilledavocado That's a more complicated question than it seems.
Historically, 7 Cups benefited from the spam because it had the effect of promoting 7 Cups in search engine rankings (Google, Bing, etc.) and it also increased the number of visitors to the website, even if those visitors were only looking for lotions
Later, 7 Cups removed the forums from the search engines, but spammers still make many (fake) member accounts, so they still boost the number of members 7 Cups appears to have, and it's possible this is still useful for 7 Cups' marketing purposes.
The latest news about spam was in the December 2019 Community Update, which seemed to hint that some action might be taken at last.
It's technically quite simple for 7 Cups to block the spam. Some time ago I made a forum spam filter for my own use and I think it only took me a couple of hours. But unfortunately 7 Cups has never been very responsive to the community's technical needs, and what might have taken me a couple of hours might yet take 7 Cups many months, or be bumped off the to-do list by something else and forgotten.
