I think it's not a crucial decision since everybody can already see who installed a hack by following the link in hack database. Eg.
https://vborg.vbsupport.ru/misc.php?...threadid=46679
So it should not be important if this information is also published in postbit. (Unless you plan to remove the other link too). Thus my vote is: Yes, and allow all users see it.
BTW. I believe it's important that *at least* hack author can see who installed a hack. All hacks here are free and may be the only way of "thanking" the author is clicking the install button. Hack authors should not be deprived of knowing who installed their hacks..
My 2 cents..
