[bantracker] Request for review of ban while it's actually a @mark

[oCean]

I got this reminder for a review '...please review the ban [...] that you set on..' etc
This is actually not a ban, but just a comment (@mark) for a nick/user with no bans set.

Example: http://ubottu.com/bans.cgi?log=40344

I don't think that any review of such entries is required

[Terence Simpson (tsimpson)]

the review code should probably check for one of '$', '!' or '?' in the mask

[m4v (m4v)]

I should request a "hack commited" status in Launchpad.
