Yeah, I know people can just ignore, etc etc. But that can be hard, and guilt-inducing, and there are a lot of these fundraisers nowadays, and times are tight. There's just something so entitled about that 'For my birthday this year, I'm asking for donations' wording on FB that really gets on my wick too.
AIBU to say that if someone's fundraising it would be a lot more subtle to create a Justgiving page and share it with whoever they choose to, rather than effectively asking every single person on their FB friend list for money on their birthday which is far more likely to make people feel duty-bound to give money they may not have?
