What is Tip4Commit?

Tip4Commit is a service that collects bitcoin donations and uses them to tip developers for their commits to open source projects chosen by bitcoin donors.

What happens to unclaimed tips (if recipient doesn't sign in and specify his/her bitcoin address)?

We tip only those developers who signed in to tip4commit and contributed to the funded project. Funds that are not claimed during 30 days get returned back to the donation pool of that project.

How can I remove my project from tip4commit?

New answer:

Just create an issue (similar to https://github.com/tip4commit/tip4commit/issues/173) and we'll remove it.

Also there is an ongoing discussion whether it is ethical or even legal to add projects to our list without prior consent of the project maintainers. Perhaps we'll switch to opt-in as suggested in https://github.com/tip4commit/tip4commit/issues/152.

Old answer:

Sorry, there is no such feature yet. Initially we thought that project owners have nothing to do with our project. Now there is a question. (https://github.com/tip4commit/tip4commit/issues/152)

If somebody wants to reward independent contributors of random opensource project, does he or she needs a permission from project maintainers? Should project maintainers have the power over economic activities of other people?

Why do you spam people?

New answer:

We disabled email notifications. We don't create users automatically, only those who signed in to tip4commit and specified their bitcoin address will receive tips.

Old answer:

We do not spam and never intended to. Perhaps in early days of the project we sent out disturbing notifications about microdonations, but that was fixed long ago, just see the algorithm here: https://github.com/tip4commit/tip4commit/blob/master/app/models/tip.rb#L115-L126

We send emails only to public email addresses of contributors who received tips for their contribution and only when ALL of the following conditions are met:

• contributor's balance is above the threshold
• contributor didn't specify his or her withdrawal address
• contributor didn't unsubscribe
• contributor wasn't notified during last 30 days (if contributor doesn't specify bitcoin address during 30 days, tips will be returned to donation pool anyway)
• project maintainer didn't disable notification for contributors of his or her project

Email recipient can explicitly unsubscribe or just ignore the message.

If there is any victim of our spam please create a ticket at github with facts. So far most of the criticism comes from people who never got a single email from us!
