In which forums is the use of "tard" acceptable?

I seem to recall it being the other way around. If no action is taken on a reported post, it means it wasn’t actionable.

From a thread asking about how to know if a report was received (because nothing ever happened):

From a thread about responding to reports:

I know I’ve seen other similar posts and I too was under the assumption that if you report something and nothing becomes of it, whatever you were reporting is ‘allowed’.

These are just a few posts I found by quickly googling the board. On preview, I see one of them is from Colibri and directly goes against the Colibri post I quoted.

“Unless a mod has positively made a ruling that something is within the rules, you shouldn’t jump to that conclusion”
and
" if no action was taken we decided none was warranted"

You can understand why, as posters, we get confused about the subject.
