I will not Speak for the Other Admins, but I (personally) have a very low Tolerance Policy of People who Spam. My system for dealing with them is as follows:
1st Offense: Warning
2nd: 24 Hour Ban
3rd: 1 Week Ban, along with a Final Warning
4th: Account Deletion, as well as the Accounts Email Address put on a watch list. if you make a second account with that Email Address, and start Trolling again, there will be absolutely NO WARNING! the second account will be deleted, and the E-mail Address will be Banned.
now, i understand there are some people who unintentionally Spam, but those will be dealt with as warnings. This System is for those who get caught seriously Trolling, Spamming, or being a general nuisance. I do not like it when People get on and treat such a nice site like a pile of feces. I am an ordinary member of many other sites, and I have to tolerate Trolls without being able to do anything about it, but since I can Here, I thought I would give a fair warning. I hope i didn't go for the Terror Element here, I just don't like when people troll, a feeling I'm sure the Serious User would Understand and Appreciate.
