I have 4 accounts and as of right now, they are all safe. I used the /warp /gate while in instances the first weekend they sent warnings, and once or twice after when lag caused me to falloff a cliff, they were short warps, and haven't used any of them in the last week now.
In the weeks before this, I used /warp a lot in instances, sometimes in open zones(I try and make sure no one else is in zone, or I wont use it) /gate when needed(Three of my toons can gate) sumcorpse sometimes, fade/succor when needed (I have an evac class) and I used the fletching mac.
I have never used Ghost, Piggyzone.
I'm using the maps now, Healer.mac and sometimes kissassist.
I have the following loaded still, GMCheck, Melee, Cast, MoveUtils, Warp, Pax, Eqbc, Addicts, piggyzone, exchange, rez, and I am still using the full compile.
Edit -- I also used the Combine.mac from time to time before the warning.
