Questions on web 2.0 link building

Hi all - I am considering a few different web 2.0 options to add to my link building - I refuse to spend $$$$$$ to catch up on 1000's of backlinks - it's just crazy and web 2.0 links seem to be the best way to go - with a mixture of regular link building etc.

I am new to this so please go easy on me, I just have some questions

1> Firstly - I know I'm late to the party with web 2.0 - but is it still doable and safe in 2022? is it worth the risk and can it pass enough juice to give me a boost?

2> If i was to follow through with this, i was considering utilizing some of the many web2.0 lists out there and creating profile/blogs/accounts etc to gain the "hopefully" do follow link - i would check their metrics first before committing.

3> I have also been looking at scraping Tumblr accounts and requesting them for the link (Also, is this still a thing and does it still work???)

4> If I create web2.0 blogs using free WordPress and Wix - would i basically create a blog with a few different pages and link out to different pages on my main site?? or just create the WordPress blog for one link to my main site? would i need to create multiple WordPress blogs if i want multiple links for the pages of my main site?

5> I'm sure I can amass 100's even 1000's of links this way. would all this effort pay off or would it likely just get me a google penalty?

6> could I just use all these web2.0 sites to replicate the same process for my other blogs?

I know it's a lot of questions but, i am new to this and i can't spend 1000's of dollars on backlinks as it's just too many to catch up on - it's simply unrealistic. Hope you can answer these questions, love to hear your professional opinions - Thank you
