A while back Elder Ballestero did a series of blog posts on ministerial ethics. They were excellent. This one was especially well written and on point. There is a proper way for various ministries to be funded, and an internet campaign directed at various saints of Apostolic churches is not a proper method.
A few quotes:
"Missionaries who get on Facebook and plead with saints for money are without scruples or ethics. Don’t give to them. Let your pastor guide your giving."
"No evangelist should ever ask for money on Facebook. Don’t be foolish and give to him, no matter if you like him or not."
"How ever it’s done, it’s never done privately between a saint in a church and the missionary."
