The short answer is "yes"! I sent messages to a PM pointing out that their were numerous errors in a profile. I included my reputable sources for my claims. One week later I sent another msg, worded somewhat stronger. This time I received a response saying that they were not in a position to help me at the moment. 3 weeks have now gone by and I have made no progress. I'll wait just a wee bit longer.
Some weeks ago I found 2 profiles the same managed by 2 different people. I sent a msg to both asking them to merge these profiles, please - there has been no response from either.
If 'leaders' are not responsive then it would seem reasonable that they should not be leaders and someone else should have this position/authority.
Maybe another group of keen, regular users should be formed called 'guardians'. The purpose of this group would be to resolve non-responsive issues quicker and, if necessary, remove PM's from profiles or be able to add people to the Trusted List - just ideas. If 'guardians' are not responsive then other guardians could remove them!!
