BIG le rage from WoW players over recent BANs

"We recently completed a wave of suspensions for World of Warcraft accounts that were found to be operating third-party software that undermines the security of the World of Warcraft client. Reverse engineering and bypassing security protocols that safeguard against client modification is a clear violation of our Terms of Service, and we regularly take action against such behavior.

Many of the suspensions issued were for 180 days, as the exploit we detected allows for very malicious activities such as gameplay automation or rotation/interrupt botting. Upon further review, we found that some suspended accounts appeared to be only using the detected exploit to do client-side character model alteration. That is an activity that we would prefer to respond to with a warning, rather than a suspension, this time. As a result, we have reversed all of the suspensions issued in this action.

The use of third party software that modifies the World of Warcraft game client is against our Terms of Service. We expect players to remove such third party software, or their accounts will be subject to further action. Any future use of software that bypasses the security of the game client, regardless of intention or gameplay advantage, will be detected and sanctioned with increased penalties." —— Kaniva (community manager)

What is client side modifications?

When a modification is client side only it means it can only seen and used by you the one playing on the server. The server admin and the other players cannot see or access your modification because it is client side only. This is the exact opposite of server sided modifications. No this is not the same as dlcs either for those who are wondering. (excelite, Anactoria)
