"glitching" on a dep shield

[fluffiluffigus]

i got this message today after standing on a depshield in overgrown.

Spoiler

"This is an official gameplay abuse warning, you have been warned for the following reason:

One of the admins saw you glitching with deployable shields on overgrown. You have been warned."

i just want clarification on if what i did was actually glitching. i believed it wasnt glitching because "the cades will break and they will be at the mercy (none) of the nords."  and i can still be killed by ranged/throwing bots. heres another thread about the same incident. http://forum.nordinvasion.com/index.php?...313.0.html
