Though i wanted to mention that vouchers, codes and so on are a risky thing to buy. Accepting those things as payment or paying for them is risky as long as you cant really trust the seller. The reason is that the real buyer of those codes can, at some point in time, claim that his codes were stolen. If that happens you lose. Those claims can be done months after selling so you should be cautious in general with vouchers. Sometimes the one youre buying from bought those codes from a provider and doesnt know what will happen too. Im not saying anything about Bob, only in general. Because thats a point that wasnt mentioned the first pages of this thread that i have read.
This is very true, however I think that using VPN/VPS services by/from him is even more risky. This is especially true for a VPN.
When you use a VPN you allow the provider to potentially be able to see all of your traffic and potentially be able to monitor any unencrypted data (or even potentially encrypted data if he uses a vulnerability like POODLE). Another issue is that he asked users to provide him with a password (and many people are very lax with their password policy and will reuse passwords, this will potentially allow him to have passwords to many users' various accounts (either bitcointalk.org or other accounts - as he can see what websites you are visiting)
That's definitely what I think. Is it not fishy that an anonymous guy sells gift codes at a 90% loss (the only obvious answer is that they are fraudulently obtained, unless this guy really is as "crazy" as he claims)? And now, he runs a free service where he can potentially spy on users and steal their information.
I'm not saying he's a bad guy or that he's doing any of this stuff; I've never done business with him, but I would advise people to be careful.
Maybe he's really CEO of JP Morgan and he gives away vouchers on a bitcoin forum in his free time. I doubt it though.
