Providing references for clients

Gentlemen,I pride myself on remembering all of my dates As I have great recall. I have always encourged my clients to use me as a reference or if they need information to please give me a call.I want everyone to be safe and I want to be helpful,Here's  the downside, Some clients that I have not seen in a very long time but have referenced many,many times always use me now I always respond ASAP so that everyone can play safe but I feel that it would be fair if you guys would use a more current provider the exception would be the men who have no one besides me some of you only hobby once in a blue moon and of course I will always help you. thank you for your consideration.
