Only if you know what it will do. Your solutions to problems always
seem to be "If I do this, will the problem be fixed?" without
demonstrating any understanding of what will be changed. Maybe you do
know and aren't showing it, but I suspect that (in many cases at
least) you simply do not understand what you are doing.

Neat. Now I know how to lock you out of your own account. Five seconds
with Google brought this up:

Can you, by reading that page, tell me what I would have to do to stop
you from accessing your login?

Also, CPHulk does not appear to have _any_ protection against
privilege escalation. It's a completely different thing. So once
again, it appears - maybe that appearance is wrong - that you have
done something that "ought to fix security" without knowing anything
about what it actually does.
