Forum subscription gone crazy

Is it just me or has the forum subscription system gone the way the rest of the forum software has..... Wacky?

I'm getting subscription emails for some posts over and over again. I mean like 5 or 6 a day, everyday. I don't mean just when a new post is added but it seems it's the same posts generating them over and over again.

For example there's a thread about dual monitors upstairs where I posted some info for Beagle, who kindly thanked me. I've had about 30 emails in the last couple of days informing that Beagle had replied. I mean I like you Beag but my inbox is awash with subscription emails. So much so I've turned them off for a while.

I haven't changed any settings and it doesn't seem to be all threads just some of them.

Is it me? 

I didn't think about that. Perhaps he's rigged the system so it has to send as many notifications as he does posts a day.
