I think that Blockchain.info don't advertise randomly using third party ad networks but they get paid directly ... so It's unlikely that they advertise a scam , however ,I found that the owner (or the OP : https://bitcointalksearch.org/topic/ann-bitbond-bitcoin-p2p-loans-248441 ) received a negative trust for fake reviews or something.
So I want to hear from those who actually used the website (for both taking loans or giving them) , I'd appreciate any honest review.
I've been following & investing on Bitbond for a while and can tell you it's not a scam. They've been around since 2013, fully regulated with over 40,000 users. The trust issue on bitcoin talk seems to have come from someone claiming reviews were fraudulent when in fact they are not. I would recommend you check out reviews online which are vastly positive. Trustpilot, or this one http://peersociallending.com/investing/bitbond-review-my-bitcoin-lending-test/ for example.
In case you have doubts about the owner, you can watch him present at Finovate, the biggest fintech conference in the world, here https://www.youtube.com/watch?v=UBCOalBIGPM
I really appreciate the detailed feedback/review , I'm not sure If trustpilot reviews could be faked or not but since the owner of the company is already known . I feel secure to use them , I guess. thanks!
