I agree with you in general, Bob, but actually I sometimes take on these as a bit of a challenge, providing their surname is sufficiently unusual to warrant the investigation, or I have other hints (such as shared matches) to point me in the right direction. I have traced several 3rd and 4th cousins this way.Always of course, avoiding 'Ma-and-Pa' and 'No Tree' and limited interest in Private Trees.
For example, a recent match popped up in my list (fairly high up at 63 cM) who had just himself and his father in his tree. Had he included his mother I'd have recognised the name immediately as one of my ancestral surnames, but all I had to go on were a couple of shared matches. Having failed to find his birth in this country, I was able to work out exactly how he is related to me courtesy of some excellent South African records at FamilySearch. I traced him back to his great-grandfather who had emigrated to South Africa in the late 19th C and who was my great-grandmother's older brother. Having discovered the marriage of said DNA match, I then found his wife's tree, which was full of detail including her husband's ancestors, thus confirming my research.
