Across the forum, there are lots of people bitching about Fiverr.
Like any other entity including you as an individual, rules are created to guide and guarantee existence. These rules do not have to be universally accepted.
The truth is the pain is real, almost every complaint I have read has lots of emotion attached to it.
Some things you have to accept fast and come to terms with for the sake of your mind.
If there are policies and rules that seem oppressive, 90% chance is that user complaints will not cause any change, especially for monopolistic businesses.
Do not be fooled, there is no such thing as privacy online, it doesn’t matter what policies or legislation governments enact, both corporations and governments themselves will have access to whatever information they want for whatever reason as long as it is on platforms they create.
They may publicly make you feel so, but the reality is far from the truth.
So, if you care about what you say or don’t, then some of these platforms are not for you. But as long as you do anything online, at the back of your mind there should be a possibility of anything happening with your data.
Your only hope is that the people using the data are adults and responsible enough.
