DA: 92 - Auto Approved Backlink Website For BHW Members

Hello guys, below links are kinda sites I build my backlinks, (Powered by phpBB) Sites, most of them are relevant to my blog niche while some are not, but I think I kinda need some advice about the sites, I don't want Google to penalize me for doing anything wrong.

So Please I need your opinion... Is it cool to build backlink on such sites or any advice you have to give me on this? Also, will it affect my site if I tap backlink from HTTP (and not HTTPS) website.?

It doesn't matter whether you get a backlink from http or https website.

If you build links from forums, you better find relevant niche ones, or some general ones but then post in relevant topics. Building links from random forums is kinda useless.
