Blank signs also happen with words and not just numbers. There are examples such as: "Thomas", "Franklin", "Henry", "Bob", "Andrew", "Grace", "Bill", and probably many others that I haven't had the time to test. Some of these only cause the sign to become blank if they're the only word on the sign, but some can stay visible if other words are also present. I really have no idea what is causing this issue, as text really shouldn't disappear like this, especially since these words (likely and hopefully) aren't on the banned words list Minecraft has.
Blank signs also can happen when you write a letter followed by a period and then some text, such as "H. Ford" (which was one alternative I tried in order to not have a blank sign when writing "Henry Ford", but both texts end up blank). The latter letter rule is very finicky, and doesn't always occur, but the fact that it occurs under some instances, such as "C. Text" and "U. Iguana" shows that there is some underlying problems in the system.
Likely, the entire censorship system on Realms needs a major overhaul to stop these issues from occurring, allowing users who are not in the wrong to write their signs peacefully. There are many other instances of signs becoming blank that I have experienced in multiple survival and creative worlds, so there are likely many other finicky aspects to signs becoming blank that I just haven't been able to test in addition to the examples shown in this post.
