Is deleting review in fisheye crucible affect source code file own which review had been created?

[Meet Darji]

Hi Community people,

I have one concern about the Fisheye-crucible & linked repository code. I'm currently using a Fisheye-crucible server (V 3.7 & V 4.7) and the system consists of hundreds of open reviews with 6-7 years of aging. creator and reviewer display as deleted users.

1. is deleting reviews affecting the source or patched code file on which these reviews had been created?

2. Should I delete these reviews with a bulk delete operation? if it is possible then how?
