I'll start this off by saying that my preferred cancer charity is the Royal Marsden (Sutton) so if you're stuck for charity ideas then give them some time/money. 

We got another charity scam flyer through the door but this one tries all of the tricks, while having no charity number or such like. As a starter it says "Clothing Collection For Breast Cancer Prevention Programm" (completer with typo) but after tha simple intro the serious manipulation gets going

DO NOT DELAY
For yourself and those who love you.

Thanks for that. The whole flyer's full of this kind of stuff.... really not nice, particularly if you have any personal experience with it. They do give a phone number of 028 3084 9971, which I believe is Newry in Northern Ireland, but I haven't tried it.

If you go to the website it redirects you to a website in Lithuania with even more sobbing rhetoric and their bank details so you can transfer your money to them.

Anyway, here are their domain details (LT being Lithuania):

I've found another good resource of scams and stuff at http://www.g6csy.net/spam/letterbox.html in case you need it.
