Le site proz.com est-il sûr ?

I've used Proz for many years and continue to do so as its a necessary evil in the translation business. They had a major problem in 2009 as their system was hacked and the hackers got everybody's details. I also get several e-mails a week from them despite always being careful to opt-out from all marketing etc. In terms of vendor quality, you have to be really careful because they have no safeguards against poor or fraudulent translators operating on there. I can claim to be a Serbian to Afrikaans translator on there, rip people off and according to Proz rules nobody can complain about it. You can only give good feedback about translators or no feedback at all.
