I disagree with take on Wikipedia or Wikimedia there was a lot of trash talk because they were totally obnoxious with their fundraising. I donated once to Wikipedia and then I was getting Jimmy Wales in my mailbox basically like everyday. That actually drove me away from ever wanting to donate to them. Then there was a lot of talking if they really are so much in need of money but that's different topic. In contrast…
I have this same feeling with donating blood (in most EU countries you don't get paid for this so it is completely charitable). If you have donated blood, every 2-3 months they will send you an e-mail for a new donation cycle. That's fine. But if you don't respond, they will send another reminder. Then a text. Then they will call you. Yes, you can just click the "Not this time" button, and click the reason for denyin…
In addition, AVIS is a very community-oriented volunteer association that builds a sense of belonging and awareness.
Organized this way, the system works.
