Hi Bryan - the new members have to go through a vetting process (i.e. me) before they're approved. So all of these "new members" have been removed

On an average day I get about 100 dummy subscriptions. So this, to me, is pretty normal. I'd say that half of the visits are from webbots of some kind - although it's difficult to say.
Yesterday and today, for some reason, there seems to be a "spike". I've had this happen once before when I traced it back to someone who included a UK Butterflies link on (if I recall) a CNN page.
The average number of visitors to the website at this time of year is about 2500 per day. Today it's at 4776 as I write this - so I reckon someone has linked to UK butterflies (possibly a link to a forum entry) from a well-visited website. I therefore suspect that this "spike" to drop to normal very soon!
Cheers,
- Pete
