Most writers on this platform are not aware of Medium’s non-inclusive policies, which is why I took up the subject.
Anyway, my current status as a writer on Medium is identical to yours — a non-paying member who contributes articles. I now find that I’m only allowed to read three articles a month. What I have discovered in my short time outside the paywall is that there are three exceptions to this rule. Basically, I can view any Medium post, which:
#I have written
#appear on Medium’s Twitter page
#are in any Medium publication in which I’m a writer
To be fair, any regular writer on Medium with a certain minimum number of views/reads, should be given full access to the site (writing a random post shouldn’t be a loophole to get through the paywall). Think about it. Medium’s whole business is based on what its writers write. And to not give these very same writers access to the site sounds unethical, to put it mildly.
Medium is pretty messed up, if you ask me.
Coming back to your question, the answer is, no, it’s not normal for you to be unable to read your own posts. Suggest you write to them. I think you should find some way to do so within their help section.
