I've come to the conclusion that GR's Hot Matches are pretty much a waste of time, particularly if you only have one Hot Match with someone else. I don't usually bother checking them unless there are at least two matches.
The problem is GR only match the name and year of birth. You will get matches with same name people born all over the world and rarely the same location your ancestor came from.
You say you've had no requests from anyone for access or info. Have you contacted the people GR match you with for access or information? It's a two way thing.
However, I agree with Craft, GR is not expensive.
