niggling thoughts about nominations

I am trying to work out what it is about nominations that I dislike. I do have some genuine concerns regarding the latest ice-bucket nominations as the charity concerned does not really operate in the way I would hope but that doesn't really explain all my feelings.
Imagine I was happy with the charity involved, would I welcome a nomination then?
Not really.
I have been thinking about this a lot and have posted some other people's considered responses to the Ice-bucket nominations and they go part way to address my concerns.
I don't feel comfortable with these charity nominations  partly because they resemble the neck-nominations where young people nominated each other to drink themselves senseless then seemingly bright, intelligent people did just that rather than let their friends down so publicly.
I was starting to feel anti all nominations and then I realised that I have actually succumbed to a nomination scheme myself quite recently which was write 3 positive things about my life for 5 days and nominate 3 others to do likewise. I did this without thinking too deeply about it because it seemed positive and harmless and fun. I guess other people find the ice-bucket challenge positive and harmless and fun.
I am not so sure though.
If everyone nominated looks carefully at the charity being supported and is happy with it then it seems fair enough that they take part but then they nominate a number of people and this is where I become more uncomfortable.
Some people may receive their nomination and feel compelled to take part so that they don't let others down but there may be genuine reasons why they choose not to support that charity at that time.
This also seems to link with those posts that appear from time to time asking you to complete a simple puzzle and then telling you if you share the post immediately you will have a happy life and if not you will be cursed. A lot of people share these posts for superstitious reasons and this only passes the stress onto their friends who are then forced to comply of have something bad potentially happen to them.
On principle I never share these posts as I do not like to give into blackmail in that way.
The two challenges are not the same but I believe them to be linked.
I think the problem I have with the whole thing is people feeling compelled to do something they wouldn't ordinarily do because they don't want to let others down or appear mean.
Please understand that if you nominate things for me to do I will consider them carefully, go ahead if completely happy but if not I won't proceed and I hope very much that this doesn't affect our friendship.  The next time you are nominated for something please only proceed if you are 100 % happy with what you are being asked to do and the cause you are being asked to support as people love and appreciate you for being the unique person that you are and so will completely understand you thinking for yourself.  x
