I used to check Free Republic traffic counts every few months.
All the free web traffic counts have disappeared, so I have not checked for many years.
My own impression is that we had a sharp drop off in FR membership after the highly aggressive "Always Trumper" mob showed up in 2016, and more drop off after the "Q" mob showed up in 2017.
Regardless, I voted for Trump in 2016 and 2020, I still visit Free Republic every day, and I still donate to Free Republic every month.
