Stingray, you are correct.
The "line TD" has absolutely no power over administrative decisions, but his/her position could be in jeopardy if s/he failed to implement all such decisions as ordered.
Whatever beefs any Elite member may have with administrative decisions should be taken up with the HA of the league involved, via e-mail, and if that does not produce a response, via e-mail to the appropriate Elite Senior Staff, through the "contact us" link.
We will not tolerate behavior such as you have outlined from anybody in the Elite community, and we have rules with teeth in them and the means of enforcing them, if a formal complaint is made. The normal procedure for complaints is via a "Player Note" entered by an Elite staffer, or via an e-mail to the HA of the league involved by a member. In any such complaint, tangible proof should be attached, usually via a "screen capture" of the incident involved.
Making a screen capture is a simple process: the key to the right of your F12 key, in the top row, is labeled "prtScrn" or something similar. Hitting that key places a copy of the screen on the clipboard, and from there the image may be pasted into any bitmap editor, like windows paint or photoshop, or into a word processor document. Once it has been pasted in, the document may be saved and a permanent record has been created of the incident.
It is never appropriate to engage in public attacks, this is a given, but please, everyone who reads this, it is also inappropriate to respond to such attacks, to "defend" the TD or player being attacked, to engage the attacker in any form of debate. If everyone would ignore the attacks, the damage would be minimized. It is when the community is galvanized into taking sides that the trouble begins in earnest.
Please do not respond to harrassers in the lobby, it only makes things worse and will get the responder "reported" as well.
