Perlmonks is a place where people should ask questions. Usually when asking a question you don't expect it to be a bug in Perl. Or if it is you expect someone else to have found it already and there to be a workaround. Therefore it is perfectly appropriate to ask on Perlmonks about things that might be bugs in Perl.

Now new bugs obviously should be reported through the proper channels. But you should encourage people to do that in addition to having asked the appropriate question here rather than telling them to do it instead of posting here.
