Mailchimp bot subscribers
Since that happened, I started to receive subscribers, even prior to my website even being submitted to search engines. I almost daily get a subscriber via the form, however the name is always something like "a8ef63d" or some random order of numbers and letters (indicating its likely spam subscribers).
I find it a bit ridiculous that mailchimp doesn't offer support unless you are paying for their service & that they start charging with 2000+ on your list. I think it is a bit suspicious for that reason that I receive so many subs after that change, especially when my site wasn't even submitted to search engines.
Anyone else notice this?
