Thanks for mentioning it. Normally the message should hide, once you click “no thank you”. But we will check if there can occur problems that force the notice to show up again.
I personally find it harsh to give a one-star rating as you seem to be using the plugin already for a while (the message appears first after 10 days of using the plugin, as we explicitly want to “not disturb”).
Hope you like the Internal Link Juicer and you have fun with it. The next time you have something for us to improve, you do not have to blow doors down in here – simply write us a notice in the support forums and we will have a look at it. Thanks and keep safe!
