Don't know about this one, but bitcoin tipping service Bitcoin Tipper http://bitcointipper.com/ is real scam.

That's a great idea about people inputting their own addresses, although I'll need to find a way to avoid permalink collision if someone wants to use the same address twice, or if multiple people want to use the same tipping address (for a charity, for instance.)

That's a good point, but I'm not aware of any wallet software that would re-use an imported key as a change address. I understand this is a strong theoretical concern, but do wallets actually work this way - especially a wallet that a novice would use? Would you suggest another way for people to claim their tips, or is this risk just inherent to this project?

(It should go without saying, but I'm not interested in doing anything nefarious with stealing anyone's tips. I actually can't steal anyone's tips - the private keys are unrecoverable once a post is made. It's in my best interest to incentivize people to make more posts by ensuring they're able to get their tips any not stealing anything.)

In any case, I appreciate the scrutiny from a security standpoint, so thanks for bringing this up.

I know blockchain.info prompts users to "sweep the key" when they try to import; perhaps you should at least use that language until there exist better methods. I have definitely heard of users losing funds because an insecure key was used as a change address behind the scenes in their wallet software. It might be a better solution to keep the tips in your own wallet and create an interface for withdrawing to specified addresses; that way no user can accidentally leave an insecure key in their wallet.

Edit: You can also give users the option to specify their address when they create the post; that's probably the best solution.

Hi All - last week I launched http://bitcoinmegaphone.com and I'd love to get everyone's feedback.

The basic idea is that you can pay by the character and post as much as you'd like. Then, people can tip each post to boost its presence on the "Most Tipped" page.

Any thoughts / suggestions?

When you want to collect your tips, just import your private key into whichever Bitcoin wallet you use. For instructons just Google "import private key into (you wallet service here)."

This is not a good idea; you should not encourage potentially novice users to import insecure private keys into their wallet.
If their wallet later re-uses your address to keep change, the user might end up losing his whole balance.
This may very well be your intention..

Thanks for being an early adopter Daniel! I just tipped you the cost of your post. (BTW, you can import your private key to your wallet so any more tips will come directly to you.)
