The aggressive sales tactics of the charity representatives at those little pop-ups at the supermarket and plazas are a bit shady as well, IMO. I usually manage to avoid them but the few times I have been stopped, it’s never a pleasant/easy experience to get away. They are trained to sell this way, and I understand they need the donations, but it never leaves me with a feeling of respect for the charity they represent.

Those people likely aren't direct representatives of a charity. The aggressive (desperate) ones are generally salespeople hired by third parties with KPIs and quotas they need to meet in order to get paid anything other than the bare minimum. Many are underpaid and exploited by their employers and only take the job out of desperation. This industry has been investigated by Fair Work previously and is the subject of an ongoing inquiry.

100%, $70 a month to restore sight? Homie I'm struggling to afford to eat and pay rent.

In fact if I was even $10,000 better off a year in my job id absolutely be dishing it out to those who need it. But hell no you can't have my data.

I know what I'm saying, give a cent to these charities and your phone will be ringing every dinner time by Indian telemarketers. It's a pretty well known fact at the moment.

They take your money and sell your data.
