If you have a very persistent person/s you can make your site or specific pages member only for a time. Do this by going to the “Control Panel”
Then “Site Pages” Each Tab will have a “Display Options”
Look for “View Level” Change this to "Level 2: Associate Access ” then only logged in members can see you page.
Do this to all pages you wish to keep non members out of.
Please do not make your home page member only, how will new users find your site if the home page is for members only?
Note that some Internet Service Providers have multiple users using the same IP address, so it is possible to ban someone you did not intend to. Please use this tool only as a last resort! If you are being harassed and the user is violating the Terms of Service, you can contact support for assistance.
You can now also “ignore” a user.
Ignoring a user will affect you only.
Unfortunately, just like in-game, there are times when you might want to completely ignore someone on your GuildPortal site. You can now do that with the new Ignore List feature. You can get to your own personal ignore list by clicking on Characters / Settings from any guild page.
Ignored users will not be able to send you web-based e-mail, and their post titles, text and signatures will be replaced with generic "user blocked, post not displayed" text, shouts blocked out as well.
