Charity Marketing

Is it just me or are charities getting far more aggressive in their efforts to get people to donate to them?

I just got phoned up for the third time in three days asking me to donate to some worthy cause.

I’ve also noted that often in town you have (paid) young students stopping pedestrians and convincing them to join particular charities. I even ended up joining and donating $30 a month or something to the World Wildlife Fund after being stopped in Manners Mall (yes she was was very cute, yes I have a problem saying no to cute females, and yes I am sure that is why they hire them)

Am I just being targeted or have others noticed more calls and the like?
