I think this basically answers your question. The cost they spend to encourage users to read/visit their website is incredibly small compared to the visibility that they get. There is little to no incentive for them to actively find users who abuse the system unless you explicitly abuse it with bots or something. But yeah, at the end of the day, nobody knows unless you ask them.

If $1 per week is a lot for you, I suggest looking at remote workers like raters who usually don't need a lot of job history. You'll earn a lot more and that should allow you to spend more of your time learning something else, even if it is not related to crypto.
