I registered as a free member of USfreeads, in order to promote my website, which is clearly an informational website regarding gardening and other things in life.
USfreeads said my ad fell into another category, which it did not, and wants me to pay them money to place the ad. Their own advertising baits website owners to place free ads, but requires you place a paid ad. In other words, they bait you with the promise of placing a free ad, but disapprove your ad miscategorizing it so they can require you to buy a paid membership in order to accept any ad from you.
As the previous complainer said, they have no email support, contact information is hard to come by, and when they disapprove your ad, you left to generalize about the reason.
I personally am boycotting USfree ads, and calling for a boycott of USfreeads.com.
