Free forever plan vs free trial plan. (comment which pricing model you use & why?)

At Linkly ( https://www.linkly.digital/ ) we are getting too many fake users using temp mails to create accounts which are causing a low response rate in our link-building network.

So, to make a more active link-builders community we decided to change the pricing model from a free forever plan to a 7-day free trial.
