Hi @itro and how are you today? Let me introduce myself.
I’m an actual moderator in these forums. I’m not perfect and I do make mistakes but this is not one of those times.
You referenced just now this topic.

That very correct reply can be summarized as follows: You (the plugin author) cannot support your customers in these free forums. Cannot. It is not allowed.
That part is not for discussion, if you have a customer and you support your paid customer in these forums then you (the plugin author) run a real risk if having your plugin removed from the WordPress repository on this site if you send them here for support.
I am not part of the plugins team but you can ask them yourselves if you choose via plugins [at] www.ads-software.com
and I am sure they’ll explain it to you.
Now about this review. As I explained above, you are using your plugin to sell your “pro” plugin. When you do that, you make this and other reviews legitimate. This review isn’t about support, it is about a user experience with your plugin.
If you do not like that outcome then please consider removing your plugin from the WordPress repository. The plugin team can assist you with that via the email I posted.
