Clearing your webbrowser, or just waiting while a page lazily loads often resolves it. Opening and closing your browser sometimes resolves it. i think rarely 3 party hacker/commentators are attracted to other commentators
moved by illness/anger and can cause problems. One Scott Wade just yesterday came to my facebook page over a comment on "MSN NEWS STUPID ****." Jest block 'em.
I would never use face book to post things on MSN.
My web site for our (My Wife's) Band according to the Gentleman who takes care of it for me reported that it has had 1,280 attempts to hack into the web site. China, Thailand, USA, and about a dozen other countries have tried to take over the web site.
Boy if you want a good web site contact Cherry Pixel Production, Salem, Oregon, to make a web site. Inexpensive also. P.S. I do not work for them. Got to give them a plug as they did a good job for me.
