Back in early 2010 when I added AdSense, everything seemed to go well. Within three months I reached the payout threshold of about $100, and I was a happy overlord. Unfortunately, in spring 2010 some guy from Belgium (according to his IP) clicked ~20 times on the same ad. I reported this activity to Google, with the offending IP address, and they quickly responded by suspending my AdSense account, indefinitely... in case you're wondering, yes, it is still banned and yes, I contested their decision to no avail.
That's totally unfair! I was reading about adsense and how to lift the ban and everyone says it's impossible.
But there's this discussion on google's product forum: https://productforums.google.com/forum/#!topic/adsense/BQYp_jvO13k
Maybe if you raised the matter in a new thread there then they might notice? Seems bizarre that they ban you for doing the right thing.
Accepting donations from members would be fine. For the older members here a cost of $10 per year is nothing. I'm sure there'd be at least 30 members who'd pay $10 from their paypal account to keep JGO going. That would cover costs for about the next 2 years.
Another option may be to use the community more.
I have a VPS of which I use barely 1% which could be used to host JGO. I'm sure others are in the same situation.
But the hassle of moving JGO to new hosts would be a waste of labour.
