So I came across this while I was searching for a font.
It seems that the links we are sharing in the forum is being posted to other sites. Plus, they already know what password we encrypt the files with. I remember a discussion months ago about the posts not having enough thanks vs. post view numbers; it would seem that this may also have an effect on it.
I'm posting this here just in case somebody has a suggestion on how this can be minimized (I can't think of any at the moment).
