My first reaction is to say that this is a bad idea as I and
many others often read old nodes and vote on them too. However,
it occurs to me that anything deserving a -- that is over a month or
even just a week old has probably got sufficient -- to keep the
coffin lid nailed shut, so maybe this isn't a bad idea after all. Personally
I don't think I've ever downvoted a post that is more than a week or two
old.
On the other hand (I always carry two), I don't like solutions where there
isn't a real problem. I think the actual number of incidents of
a person being singled out and bulk downvoted is very small and we have
to consider whether such a strict voting limitation is warranted. Perhaps a
better solution would be to detect multiple downvotes from a
single voter within a short period of time, on nodes which had
postitive rep. to start with... but compared to your quite simple solution
this better protection would probably give the creator a fit!
