To object to being invited on FB to give money to a charity ?

I almost fell for this when FB generously offered to donate £2 to a charity of my choice on my birthday. I clicked on the link, thinking how kind of them and immediately realised that I was setting up a request to all of my friends ( four at the last count) to donate as well. I cancelled it and suspect that FB make money from this in some way, otherwise why bother? Perhaps your friend was caught up in this too and hasn’t realised what has happened.

No, you are not mean. There is too much asking for donations on Facebook - and too many private messages asking you to do this or that and pass something on and so on, loads of invites to events you haven't time for, and aren't much interested in anyway, it gets very tedious to be bombarded all the time with all of this!!
