people sill fall for this BS?
what did you expect?
you get what you pay for.
these shitty services will only harm your SERPs. you obviously can't get quality legit backlinks for that price, just poor quality spammy shit that will get your site shit-canned. I warned people many times on here but there are still suckers falling for it.
don't be a lazy fuck and do your link building yourself manually. that works best and long-term.
