Is guesttoguest.com Safe?

Warning about Guest to Guest I'm posting this to warn other potential customers of this site that we had our identity stolen through this website. As part of the registration process, Guest to Guest ask that you email them scans or copies of proof of address and ID. We sent a scan of a utility bill and passport to the address requested, asking for confirmation that it had been received. We did not receive confirmation, but instead another request via their website for the same information, this time to be sent to another email address. All this was on their own site and using a cloned copy of their official pro-forma. We then received an email alert from Guest to Guest that someone was operating a scam from their website and that we should not send information to the address provided. Unfortunately this information came too late as we had already sent the scanned documents to the phoney third party. If they had telephoned us straight away our documents would not have ended up with a third party. At the same time we also received a spoof email from PayPal (the payment method we had used) but this time we ignored it and reported the matter to PayPal. Apart from the fact that this incident set of a nightmare of having to contact our bank, the police, passport office, etc., etc., and has put us at risk and expense, and we still don't know if someone will use our identity to defraud us, instead of apologising and offering to compensate us, Charles-Edouard, one of Guest to Guest's directors, started providing a list of excuses including that they were victims too and that this sort of thing is common. They simply would not accept the fact that they had not provided a secure system for taking payment and verifying identity. They did refund us our 25€ registration fee as we requested, and did apologise after we criticised him for his attitude, but that was it. They have still not accepted any responsibility for the breach of security. So please be very wary if you intend to use this site.
