I own several forums with a lot of posts (possibly millions messages)
I've used adsense for 9 years, no complaints whatsoever from their part until last august, google sent me exactly 4 messages like this in 10 months:
"You have 3 working days to make changes to your site"
I always replied quickly, but I missed the last one; my email server was down the day they sent me the message, so I didn't even notice it until they disabled serving adsense on my website & sent me a message telling me about it:
"Google AdSense ad serving has been disabled to your site"
Turned out, some moron spammed my forum with crack/serial number request, google rightly didn't like that.
I deleted the spam, appealed & explained, they re-enabled adsense for that website after 4-5 days.
I told myself: lesson learned and started watching adsense control panel's "messages" section every day.
Today (exactly 3 weeks after this last incident), I got another "ad serving has been disabled to your site" message for a different website, only this time they did not ask me to remove the content before:
Google just directly disabled serving ads on my website without prior alert!
This time I was online when their system sent the message; I immediately did a manual scan, removed several spams that went through (all within the hour), then I appealed and explained (I also complained that I didn't get a warning)
I've been a good citizen for more than 9 years, never had any problem, never attempted anything even remotely unethical. Adsense earnings has been my main income for years (I kind of regret that now), I'm not stupid to jeopardize it, and I'm not going to do that any time soon!
But not giving me a warning left a very bad taste in my mouth, it's as if they put my account under close watch or red-flagged my account as a potential cheater or something, and I don't like that.
My question is: Given the situation, am I at risk of getting my account banned? Is there something I can do to avoid having my account banned (if such violation gets repeated (*)? Is there a way to explain to google that it's impossible to have full control over user-generated content and that this is NOT intentional in any way?
In other words, is there something I can do to get my account back to "normal" (with "green lights on") the way it used to be?
(*) The fact is, the amount of data to monitor is too large, I put an aggressive home-made spam filter (like 8 years ago), I frequently manually review threads. More than 99% of my forums is clean, I don't think there's much else to do.
Any advice would be more than welcome,
