I saw a thread on BHW where people are using Micro Worker sites to get comments dumped on TikTok similar to how people use SMM panels for IG (or used to at least). The list he provided was the following:
SeoSprint.net
ProfitCentr.com
Vipip.ru
Vktarget.ru
Wmmail.ru
WMRok.com
Socpublic.com
WmZona.com
Fastprom.net
Rubserf.ru
Ex-Promo.net
No idea if any of these sites are good or not but there was a lot of talk of this generic comment dump strategy working well on TikTok currently.
