That is a good strategy. Others do not do the same.
There was a case on this forum where Mattelot claimed the same thing before and even after the MVP Leviathan provided a screenshot that documented that not only did Mattelot read the supposed “hidden reply” but also that Mattelot edited a prior post made ~9 months earlier in response to that old post being quoted in the “hidden reply”. Mattelot apparently forgot that edited posts have a pencil icon and time stamp. Even after the MVP provided the screenshot, Mattelot continued to deny reading the “hidden reply” and the fact of the edit time stamp of his old post, despite what everyone could see for themselves with the MVP’s screenshot.
