And, there's the rub.
Understanding is vital in such cases. Really.

The large majority of people* who are on the "receiving end" of such a
post, and the majority* of people who read it, will see such an effort
as a taunt or similar. It may be that if you were on the receiving end
of such a "missive" that it would not bother you, but that just makes
it the more important that you accommodate other people's 'weaknesses'
& peccadilloes. A bit of explanatory comment, softening what otherwise
can easily come across as a Sabres-at-dawn gauntlet-slap across the
face, might go a long way to making such offerings less offensive.

The admin comment that you found excessive was primarily unrelated to
the manner of delivery of the above missive - it related to noising up
the PIC tag.

Indeed.
In internet text communications "The medium is [at least an important
part of] the message". Friendly living requires more care than we
might randomly put into something.
