Anti-Spam by CleanTalk broke my form, each real entry was accompanied by a spam entry, I do not understand where the data came from but after disabling Anti-Spam and testing the form the entry was back to normal.
I now have disabled Anti-Spam and set up WP-security (enabled: block Spambot comments & Basic Firewall Protection). I do not know if this also filters submissions in the Mollie form but we’ll see.
