Publicly accusing you of fraud is at the very least malicious disregard for the truth if it's a false accusation. This is supposed to be Hacker News, not Character Assassination News. (That's Twitter.)
Never said it was fraud; it was a huge disrespect to my data, as if it was deliberately deleted and not data loss, it only worsens the situation - I did not get any warning; I did not get any offer to upgrade to keep my data! I will search for the payment. I could be wrong, my hundreds if not thousands of stored links, and hours were lost due to this disrespect. Look at the pricing page for this "new" service - it screams the same attitude!
You didn't say use the word "fraud," but the scenario you described—where Stavros accepted your money for a service and then chose not to provide it—would amount to him defrauding you.
From your perspective the difference may not be significant: your links are just as lost either way, and the money you might or might have not paid for the service is tiny compared to the time you had invested in creating the links. The difference, from my perspective, is that setting up a free bookmarking service and then shutting it down without enough warning is not a very rewarding activity, so it tends to be a self-limiting problem; by contrast, selling a paid service you then don't bother to provide can be extremely lucrative, like spamming, so it's the kind of problem that tends to grow rapidly without countermeasures.
That makes it a considerably more inflammatory accusation.
