Maybe the person just has a lame name and wants it hidden.To be honest, I'm not sure I get the (very popular) motivation to "hide" the engraving. All my ARs are engraved right over the hammer/trigger pins, in the same font as the manufacturer's.
I match this font:

Looks pretty normal. Granted, this is an AR-specific example, but you get my point. AR lowers are commodities, unless you're talking about something special like a ban-era "LEO Only" marked Colt 6920 or something like that. Beyond that, I'm not sweating the engraving.
It’s like the same reason I kind of want a lower from SLR. How do you compete with a city name like “Winter Garden”?
