Oh? Well if it so obvious, then it should be easy for you to explain.
While you're at it, maybe you can explain why it was OK for him to go around being needlessly antagonistic or insulting to potential helpers. Realize, he either had the donor list and knew who they were on OCDO, or didn't. If he knew, then he was deliberately disregarding their help and being needlessly antagonistic. If he didn't have the donor list or the connect to OCDO usernames, then he was being needlessly antagonistic and insulting to people who might have been helpers.
So, go ahead and explain to me why I should endure the needless antagonism and needling little insults of somebody I helped.
A donation, freely given, is freely given. To bring it up again as some kind of chit to be cashed in, means it was never freely given--despite claims to the contrary--and was instead given with some intent of it creating some on-going obligation.
Make a loan, go into a business partnership, or even form a friendship and one may rightly have an expectation of an on-going obligation of some sorts. Ditto if help is given with expressly understood conditions as one might do for a child attending college.
But a free-will donation is a freewill donation. The donor should expect NOTHING in return; and the recipient should feel zero obligation. Any other arrangement is not a freewill donation, and if a donation was made under pretenses of being a donation when the donor really held some expectation of obligation, then the donor acted dishonestly; he imparted the money under fraud on his own part.
Quite simply, Citizen, you've demonstrated that you violated the NAP by acting fraudulently.
It is also boorish, rude, and uncouth.
Do you need further explanation? Are anarchists so opposed to any rules they are unable to deal even with voluntary social mores?
As for your supposed mistreatment at from skidmark, you might grow up and learn the difference between disagreement and actual insults or antagonism.
For example, you've repeatedly accused me of "disrespecting" you or not "treating [you] as an equal" because you dislike my "debating style". Such assertions are ludicrous and juvenile.
I would suggest you go attempt to redeem yourself by frankly admitting the gross social faux paus you've committed, and asking frankly for forgiveness. But with this post I see you've doubled down in justifying your conduct.
Good luck with that.
