Yesterday I had 1 person opt in to my list. The average is 5-10. Today so far there are 162! It started at 9:00 this morning, and since then someone signs up every few minutes. This list is single opt in, and I'm afraid SpamZa or something like it has gotten ahold of my squeeze page. Has anyone else experienced this with a list lately? I'm not sure what to do about it but am seriously considering going to double opt in.
