Post links to 'cheating using the soundmod' tracks here:

This may be (?) a better explanation: The hacking itself can be seen as a misdeed if Oleg personally dis-likes it, which I assume. Using the hack/mod tools to cheat in anonymous public servers is a different misdeed which is not related to using the tools for non-cheating purposes.

The mod/hack tool can have no negative effect on any type of gameplay. Only the online players in anonymous public servers can cheat in anonymous public servers and so negatively effect only anonymous public server gameplay.
