Rejection of my island with reason 1.2 Keep Personal Info Private

So my island got rejected, whilst it was actually doing really well.
Okay, so there seems to be a problem.
I contacted support and asked what the issue/problem was, so I could point my attention to it and fix it immediately.

However, they have come back, with still the same reason, 1.2 Keep personal info private.
With additional reasoning, they have found a chat method on my island.

The only thing I can think of is just normal voice chat.

So i can not be that.
The map is just a deathrun map, yes there are a few billboards here and there, but that does not say anything personal.

The reason was specific there is a chat method on your island?
How?

Has anybody else had this before?
