[linux-lvm] Snapshots & data security

Hello,

Could someone please clarify if there is a legitimate reason to worry about
data security of a old (removed) LVM snapshot?

For example, when you lvremove a LVM snapshot, is it possible for data to
be recovered if you create another LVM and it happens to go into the same
area as the old snapshot we lvremoved?

If this helps clarify, do we have to worry about security scrubbing a LVM
snapshot for data security ?
