Holding a DWA licence isn't generally speaking a way to "
avoid having to open to the public" - without a zoo licence he cannot open to the public full-time, this is true, but the primary purpose of obtaining a DWA licence
isn't to avoid the public.
Moreover, you say elsewhere that
"my point would be don't have the DWA license as they are public record" but then acknowledge that zoo licences are also public record.... so you appear to be creating a bit of a catch-22 as far as privacy goes.
The "general public" won't exactly make searches on Google to work out what species a given private keeper holds under a DWA licence, either.
Much as a DWA licence isn't for avoiding "
having to open to the public", a zoo licence isn't for "
hiding what's on site".
You obviously haven't paid attention to how often I post bemoaning the tendency of some members - especially our younger contingent - to post wild and unsubstantiated speculation if you think the moderators don't raise issue with such things

in this particular case, one of the issues is the fact people jump from
"a licence is held for species X" to "
he must therefore hold species X now", as
@ShonenJake13 said upthread.
