Seems that most links in the Commercial Support page [1] in the Rails
wiki nowadays point to some variation of pbwiki.com. There’s more than
80 versions of that page and the spamming has happened quite a while
ago, so it’s pretty hard to rollback the spam without losing a lot of
valid changes to that page. So I suggest everyone at least fix their own
information as soon as possible.
