merged profiles

I wish I had never permitted any merge I want to delete the whole thing because the merged profiles are BOGUS repetitive and hinder my work the people who run this site should take notice and rethink what they are doing In Fact 98% of my family tree may not even be accurate as it hinges on one link that has been brought into question Likely the hangers on are simply mergeing to increase their tree and have not even done the research
