I'm not sure if anyone else is experiencing this or not but I thought it would be worth the time to mention.
When I was running 7.0.x I would get anywhere between 70 - 100 spammer sign ups per day. Now that I have upgraded to 7.1, I am getting around 5 - 10! Not sure why and I'm certainly not complaining. Just curious as to why this may be.
Thanks,
Mel
