Notify me spam

[Slavomir]

Hello

For the past three months, I've had problems with fake users signing up for the waitlist through the "Notify Me" function. This only affects two out of about 90 products. These two products are not sold out, and the "Notify Me" button does not appear on the page. They are probably just using the URL link to the "Notify Me" product page. Every day I have to manually delete users from the waitlist directly in the database. I've tried searching the forum to see if anyone is experiencing something similar. Without success. What can I do to fix this?

This is what it looks like in the server's error log:
