Well i use CE 5.2, i tried wall climbing plus speed hacking yesterday for some few hours of raging.. I don't think i was detected since i was just looking like i was major lagging, only when i climbed it was visible.. (tried on trial account, not bannet today)
Remember that when you download CE 5.2, be sure to download that little prog that patches CE to have no window name made by Relz..
And make sure too, that you have hidden it in kernel and user mode under options as well
