> In some countries it is illegal to opt someone into services they didn't ask for.
Nope. You are not a part of service unless you accept the tip.
> In some countries it is illegal to send unsolicited emails about services.
True that. This should probably be fixed.
> In some countries it is illegal to accept or solicit donations without registering first with tax authorities.
Donation does not exist unless you accept that bitcoin. This is not a problem of tip4commit. It's a problem between country and it's tax resident.
> In some countries it is illegal to suggest a financial relationship between yourself and another person/entity when no such relationship exists.
Once again. Relationship does not exist unless you've created it by accepting that tip. As for suggestion - they are only suggesting that you can create such relationship.
> In some countries it is illegal to pay out to people without also filing tax documents to track the payment and provide the recipient with records they legally are required to keep.
PEBCATR - Problem exists between country and tax resident.
If those are really problems - you have problem with your gov and your laws, not bitcoin or tip4commit.
So, because you are philosophically opposed to certain laws, I should have my inbox filled with a tipping "service" and my name and projects listed as available to donate to, on a donation-collection site I refuse to do business with, and have no ability to opt out of it?
Protip: close the /r/bitcoin tab, close the mises.org tab, and learn to be a decent human being.
