because of privacy regulations there will never publisched a date für some domains like .de
So it schould be deactivated in reporting if there is n/a data. Or it should be possible to deactivate it for custom set tld like .de
cheers
Domain information can be entered manually even for TLDs that are not currently supported: Domain Monitor - MainWP Knowledgebase
However, I can see the reasoning behind wanting to completely deactivate monitoring for certain TLDs such as .de or set them to be excluded from reporting.
