It took until I spent £80+ on bids to realise that a lot of the jobs needed' by people must be fakes. As soon as they view your bid, it's cost you money. As a small business trying to get leads, its definitely turned out to be a very costly way to get clients. Every bid has a different price. They might want to try doing a flat rate for all potential clients, regardless of the intended job.
Some people have ratings, yet there's actually no way to see their reviews or why they've been given those ratings in the first place. Or whether their requests are valid. Which then leads me to believe that the majority of it is fake. Anything to try and get the money for bids. Pure and utter scam!
