I'm not endorsing warping, but here is my conclusions on the topic.
1) In the last year SoE seemed to have stopped checking logs as often. This doesn't mean they wont start again, it just seems that since very few people are doing it these days they are not putting it at a high priority. Some of our coding has changed a little, which in theory might of made it undetectable, but i wouldn't count on it. We really have no way to figure out what is flagging active hacks, our end conclusion was they are doing a distance check on there servers to see if the character could have physically ran that far in that amount of time.
2) Most of my test accounts for warping that ate multiple suspensions in 2011/2012/2013 are still active. The only ones that were permanently banned were the ones that got suspended 4 times. To get suspended four times on an account it took about a year and a half of warping.
There was a big debate about whether to stop releasing active hacks, the conclusion to keep both sides of the fence happy was to make it so people have to know the risks involved by physically editing a file to enable them.
freewilly did do a lot of testing with us, so would know more than most about this. I stopped making test accounts at start of this year.
