When in doubt...?

[corinthum]

How conservative or liberal are we being when accepting or rejecting a
post?  

For example, I just looked at a post that introduces the "Lily's
family might have all been wizards, and Petunia a squib" theory.  It
doesn't provide any real canon for the idea (just comments that
Petunia seemed jealous of Lily).  I don't know if this was the first
time the idea was presented, but I know it's been discussed in much
more detail since; this post wouldn't be very useful to someone
looking into this theory in detail.

So, accept, since it does suggest a valid theory?  Or reject, since it
doesn't really contribute anything significant to said theory?

Thanks,
