Call it what you will, its still the fact of a subscription for a mod.
Another issue is that if you are "selling" the mod i actually expect support for the mod. I hate to say it but your history shows you dont really update the mods based on feedback (no, i am not talking about guess elo).
Also not a huge fan of the fact you edit the main post which was upvoted for "hype" reason and not mentioned a paywall or whatever you call it. And now its showing your Boosty as if people upvoted that. Regardless if people find it good or not its just the fact that the up or downvotes where for something else
