What about this.
Ballers and I work at SYKES where there are 100's of people running off of the same network. And there are several more posters coming from there.
The computers DHCP retrieves a new private IP address every morning and all browsing is done by 1 public IP address.

Wouldn't everyone at SYKES be recognized as a single IP address?
Can you track it by MAC address?

Yes, you are right. Registered member or not, a person savvy enough can proxy to bypass a ban. I am not aware of any process to reliably capture the MAC address. However, those can be changed/spoofed too.

I do not ban non-spam IP addresses because many schools and workplaces share the same static IP.

IMO, if a person is that dead set on causing trouble, then they will go through the registration process to do so. Realistically, the only way to control all the content is to moderate every post from everyone. That is definitely not an ideal solution.. All we can do is remove the content when it violates the rules, and move on.

This is another reason I want to implement the dislike button. If the community dislikes a post enough it would send it back to the moderators queue to be reviewed. This would allow the whole community to moderate the board. But even that can be abused by somebody dead set on causing trouble.
