How can there be taxation consequences unless you act to set up a bitcoin address and accept the offered tip? If you've done all that, I think it's clear you know what you're doing. If you don't do that, then the money (apparently?) returns to the project you committed to, from whence it came. The only way there could be tax is if you receive the money, and that can only happen by you deliberately becoming involved.
> How can there be taxation consequences unless ... Tax? Perhaps not, but the OP was talking about tax and other legal consequences. These can vary wildly from country to country. My local legislation requires applying for a permit before asking for donations. If a 3rd party would add my projects to this website, I could face criminal charges and the proof of burden would be on me.
Some project on github is not even remotely your biggest problem here.
