I have an issue, recently I've been getting bots that subscribe to the newsletter on Magento site, which doesn't have any guest email subscription forms.

I can't seem to trace how they end up signing up. Are there any Direct links bots could punch into URL that ultimately signs-up for the newsletter? E.G.: newsletter/subscriber/new?[email protected]
I see some logs where bots get a response
