Spam, too much, too often...some solutions
Easiest cure to a large number of spam...free accounts can't send tells. They can't join an fc, they can't trade, don't let them send tells.
Monitor low level account for rapid fire tells to many people that are 90% identical. This is simple string comparisons and if a low level character sends off 10 tells that are pretty much the same to 10 different people really fast, then temporarily suspend their ability to send tells till someone reviews the tells. If they are not spam, then unsuspend them, if so, only 10 people get annoyed by them..far better than hundreds.
How about an option to only accept tells from friends..kind of like mail can only come from a friend. Then the people I might like to get tells from can send them to me and the spammers cannot.
A nice option would be a tell filter that can be set by us that we can ignore tells that have certain keywords in them. As the spammers change the way they put in their site, we can adapt the keywords.
