May have been that particular seller. There are so many sellers on Amazon. Amazon isn't banning JCrow's lugol's iodine or any of the other brands. Sounds like your seller is getting banned. Find another seller on Amazon for you JCrow's brand. Other sellers there do sell it.
Source: Easily go look at Amazon and see. Simple.
I just did it. And also no problems re-ordering mine.
BTW - also no problems with the Nascent Iodine.
Still available on Amazon and other places.
