What happens if I use shitty backlinks

If you want to test, than test it.
Use a dummy page. Yours or one that you can find on the internet. See how it goes. Does it's rank improves?

Or you can read the reviews and ask for samples.
One that you can find on the internet? Are you suggesting to send shitty links to a strangers site and see if it improves the rank of a keyword? Hmm.
 
Don't waste your money with web2.0, blog comments or PBNs. These will all eventualyl get deindexed and your site will fall off the rankings and all your link building efforts will have been wasted
