people are worried about getting banned from official
WoW servers if they are also using private
WoW servers with an edited realmlist.wtf and bad cache and wtf data.
here is a solution to this...this is a hacked
Wow.exe that uses realmhack.wtf instead of realmlist.wtf, saves the newly created Cache data is saved to Xache & WTF data to a new XXX directory.
keep your official side official and private side private 
instructions add Wow2.exe to your World of Warcraft folder, then place realmhack.wtf next to realmlist.wtf.
thats it use
Wow.exe for official and Wow2.exe for private
WoW-3.0.2-PrivateHack-1.1
