The board wasn't hacked. Some members accounts got hacked by some of the 541 people.
Back in 2004 when Power Ranger Empire first opened, later in that year...a member named Phantom541 (female member) who was part of the staff...she did something back that was against the board rules....she got demoted for doing that. She got upset that she got demoted and wanted revenge. She declines what she did that got her demoted. A year after she got demoeted, she gathered some of her friends that were defending her calling the group, the 541s. What they did was go to any PR boards they find that is very active and cause havoc by hacking various members' accounts and spam by PM, emails or IMs on Instant Messengers. They'll stop and go away after awhile if we ignore those emails, fake IMs and PMs.
Phantom541 has issues in her life and around people by the way. That's why it happened.
That's what was happening at RangerCrew for awhile.
