I quite like the shit it stirs up in the fandom (I hate that word) when someone attempts to wade in and tries to educate everyone about fan etiquette. The amount of overreacting is so staggering you can only laugh at it all. I'm sure Tom is beyond giving a shit at this point (well, until Thor 3 - if he's in it, when he might need them all back for marketing purposes).
The best ones are the white-knights who come up with these charitable endeavors to make amends and convince Tom "we're not all like that". So far we have a fundraising appeal for the Donmar Warehouse, a blood drive (organised under the pretense that it was done for his birthday but is primarily because this particular fan is desperate for Tom's attention) and a letter of apology currently being drawn up by a small group of fans because some people stood in an airport arrival lounge to get a picture with Tom and they feel this has brought the fandom into disrepute.
