i might have a screen shot before , during and after i tried his hack , but i would give you the opportunity to try yourself.

Instruction :

- mine for a week or more without installing his hack , but make sure his program never installed (run as admin) before on that machine what u going to use for testing ... make sure your rig was hashing continuously without any reboots , open cl hangs , miner restarts
- after a few days or week you going to get a stable hashrate ,make sure your rig was hashing continuously without any reboots , open cl hangs , miner restarts
- install his software , and make sure you run the hack as a admin ! so the hack can modify a few things on your system
- let the system run at least for 48 hours , more is better
- after this you going to see something not right with your graph
- stop using his software you might going to notice that graph is still not right make sure your rig was hashing continuously without any reboots , open cl hangs , miner restarts
- Reinstall , or restore your windows  , and you will notice your graph is going back to normal make sure your rig was hashing continuously without any reboots , open cl hangs , miner restarts

if you have one or just a few gpu , you probably not going to see any different ...
if you try this with 50+ gpu .. you might will see some different ... this happened with me with 2 different 50+ rx480/8gb gpu setup from different IP's

everyone can decide if want to use this hack or not ... I created this topic with my own experience and named:
"Claymore's Ethereum Miner with reduced DevFee v3.4 - SMART SCAMMER ? "
did you see that questionmark there ?

i did not said he or she is taking mined eth away from you
i did not said his program is a virus or trojan
i said used this at your own risk

please try it yourself and share your experience with us
