Though thanks for the feedback and helping me out. Regarding shakepeare apps, @Alex Gleason et al haven't show any interest yet. I will consider blossom, but yes my current understanding is that relays are free to block these events as they will. However, incentive-wise, if they do so, I may let their customers know that these paid relays are offering 1GB of storage just because the users will never use it because it will take forever to reach 1GB with only text notes.
