Considering that's (AFAICT) my only comment that ever ended up dead, I'm guessing it's a word-based block. Which is amazing considering Wix itself would likely trigger the same block if HN were German-speaking.

It's interesting that someone would remove that comment.

Since they were [dead] pretty immediately I'd guess something automatic hit them.

That said, I think they overdramatise the issue. Yes, the naming is unfortunate, but it's not that much of an issue.

The naming is unfortunate, period. I'd be surprised if any German business uses them at all.
