I just received 20 submissions in a form hosted on my website within 2 minutes. The only field that is filled in says alert('TK00000025')
and each submission increases this number up to alert('TK00000036')
. The field switches between forms, so one form has this in the name section with the next form having it in the email section. After this, there are four blank entries.
What is this and why did it happen? Is there anything I should do to prevent it?
