Technically, spamming isn't & was never allowed/authorized on Zenyte (see rule #1). So, if he was indeed spamming, he should have been warned/punished.

When it comes to the Help CC, I totally agree with you; it is & has always been up to the Staff members' discretion to authorize it; it really depends the timing in-between the messages.
