Why send this scare tactic message?

This evening, I get a message saying: " you are soon going to reach
highest number of clicks that your subscription permits.
You have left about 10% to reach highest number of clicks on the subscription that
you are using at the time."
I went straight away to set up the paid membership.
Then I found disappointingly that the proposed solo ad campaign that was meant to run today clearly has not happened. Qlike is showing 38 total clicks. The free account permits 500 not 50 so why are you sending messages like this?
I now need to go find out what heppened to the solo ads I paid for.
