Hope things work out brother. I can understand them thinking you might be playing a few accounts if you were raiding them from time to time. As far as the pushing rule goes, yes this would be pushing except you eventually gave the res back and likely even more so for their advancement which is fine by Matt’s post on the subject when moons came about. Hopefully we will be enjoying your presences in game soon. =) Take it easy brother.
Also on a side note they should be able to see that all these accounts were on a different IP before you returned home from across seas and that the same IP problem has only been a recent one.
