There sure is a lot of debate going on about this topic. The main issue here seems to individuals contacting other people in a harassing/obscene/threatening way, while using the website features of GreekChat and/or other Internet services.
Just about every single Internet service has rules (aka terms of service / acceptable use policy) regarding the use of their services. These rules govern the use of services such as instant messaging programs, email accounts, web host providers, Internet service providers & websites such as GreekChat.
The rules for using GreekChat are posted at
http://www.greekchat.com/gcforums/register.php and must be agreed to before going on to register with the site.
There's no reason for anyone to have to tolerate abuse from another person using a GreekChat service or those from another Internet provider. I encourage anyone who is contacted in such a manner by another GreekChat user to send details of the situation to me via email at
john@greekchat.com In order for me to be able to take action against abusive users of the site I must be made aware of the situation.
And, while I may not be able to technically do much about users of other networks - I usually can be helpful in finding where to send complaints to these other networks.
