What Happened

The TXT record for 120oxfordstreet.co.uk contains only the `@` symbol. The admin almost certainly typed `@` into the TXT value field when they meant to put it in the host/name field (where it represents the root domain). The result is a TXT record that says nothing except "at symbol".
