Maybe assess the argument by the first two studies. If either of them do not support the point (or as has frequently happened for me, actually oppose the point) then you can reply for posterity and no one else needs to replicate your debunking effort.

“Your first two studies not only don’t support your argument but invalidate it, and I stopped reading after that.” ends most disagreements.

You will have probably done more work than the poster who often has just discovered keyword searches and related articles in google scholar or science direct, but everyone will learn something.
