It's a myth - be interesting to know how it started.

I think it dates back to Hubble's early days, when instruments such
as ESA's Faint Object Camera had very strict brightness limits, and
would certainly have been destroyed by observing the Moon. Newer
fangled solid state imaging sensors such as CCDs have no such
safety limits, and in fact Hubble used to "observe" the Sun in order to
flood WF/PC-1 with UV to mitigate its QE hysteresis problem.
