UPDATED AGAIN: Pastebud founder, Jed Schmidt, via the comments, directs us back to Technologizer (see link below) for his update on what was happening:
I’ve updated this issue over at Get Satisfaction, but let me just summarize what exactly was going wrong: you were inadvertently forwarding your emails not to your secret pastebud address, but to the address set as the from address for these emails, which was email@example.com.
This happened to other folks too; instead of sending email to firstname.lastname@example.org, they were sending to email@example.com. And everyone who was doing this ended up sharing the same clipboard.
Anyway, I just wanted to let you know that we’ve fixed it, and the changed will be live by the morning.
PREVIOUS UPDATE/PRIVACY WARNING: Technologizer is showing that they're getting other people's clipboard data in their paste results, including complete emails:
Pastebud’s site addresses security, and says it’s “safe enough” for general use. Based on my experience so far, I think not! But I don’t know if I’m running into some bizarre quirk or doing something wrong, or if this is happening to everyone who’s trying Pastebud as I speak. I just know that I’ve come to the conclusion that using a Web service as a substitute for a feature that should be in a device’s OS may not be such a great idea after all.
This might be a temporary glitch on the server side, but it's a very disturbing glitch and one that might just be a deal-breaker for the security and privacy concerned.
