Ive used wpe pro back in 1.11 patch for a hack I found and my accounts are still active and running. And the hack I found was more serious then this one so I don't know why people are crying wolf saying they will be banned or they can't use on their main accounts.. Gess one my main accounts has still got the old vanilla titles, mounts and yet I wasn't scared or crying that I used this.
If your smart you can hide wpe in memory to not be scanned by warden but even if you use it the chances of being banned are small.. The other way you could do this is not spam the macro, instead use it like you would be using it to craft items then train your skills then do again. I only used it to 600 cause in reality you can farm or buy mats on AH to get to 600 in 1 hit so if you went slow it just looks like your skilling like normal.. If you spam it then it looks a lil suss more so if they are bothered to scan through millions of logs for people who used it and skilled up really fast without training.. Just my 2 cents
