Any good possible alternative to Linktree for link building opportunities?

Hello!

I'm building high quality ******** based backlink pyramids for adult niche related website in hope to get ranked up in SERPs. In that case I'm using all types of backlinks I can, from profile ones to social bookmark. Linktree is bio ******** backlink type and I'm looking for possible alternatives. Can anyone please share something? Its hell to build high quality backlinks for porn tube website. Please, help! Thanks!

Links from shell - the most blackhat method of LB,
PBNs - classic, man
guest posts - expensive ones because of adult
forum links - cheap solutions with opportunity to build many many links from unqiue domains
contextual links - also cheap, but can be problematic a little bit with adult

and Use the pyramids with those options.

The links you are building over can low quality ones , if they are low quality they would be surely take hefty time in indexing as well , so better to build all quality ones with good traffic

For biolinks heres a platform that is self-hosted: https://66biolinks.com/
