You want a drug that will make you actually love exercise? This is no secret. It's called testosterone. You can actually get pure testosterone prescribed to you in the US if your levels are low, but this might not be much. Alternatively, you could get it from steroids. Carefully.
This is completely serious. Few realize how what a powerful effect testosterone can have on how you mentally feel. Like Arnold said, "You feel like you're cumming all day", among other positive effects.
Unless you were holding irreplaceable information ransom, or causing them some ongoing embarrassment, the answer is zero. I've tried this experiment...
Have you checked to see if you can use cookies or IPs to track spammers? You should be able to find some common trait, unless it's all generic bots and bots are easy to defeat.
It's just not big enough of a target for typical spam. For your case, if it's real people that you're having a problem with then you'd be well served to just put up a big warning against off topic posts and advertisements.

I have a community that grew to 50,000 members in the first year and still growing, but now much more slowly. Please tell me where this friend is that I can sell it to.

For a while I thought that it would at least reflect well on my resume. I've had it on my resume for a while now and no one has given a damn. No one person has even clicked the link...
To advertisers it's worth dirt because it's mostly just existing members visiting again and again.
The valuation of online sites really presents a "Winner takes all" effect.
So, why would someone shut their site down? I think there is a Picasso quote to this effect. The idea is that it's an insult to the value of your time, and to your entire field to sell it at 100x less than it cost you to make.
