hi,
I inserted the string in the two form tags,  that are not in the item.php but in inc.seller.contact.php (pop theme)
I did a test sending 3 emails with the same text, sent to 3 different listings, but no block user.
I do not understand if the plugin is acting against spam that sends the same email to all listings.
thanks

Plugin does not have any impact on emails.

have you a plugin emails control? or emails moderation?
yet..
you are planning to do this as an update or a new plugin?
it would be in great demand.

thanks

Will consider it.
