Possible WP:SOCK or WP:MEAT 

Both User:Westbury Nernewtes and User:Pightley created near identical articles (Westbury Nernewtes and Manor of Pightley) about something to do with British aristocratic families or estates, it's not clear. They've also repeatedly removed maintenance templates from both for no good reason, including ones you had placed . They also tag-teamed to created  Category:Manor.

One admitted a COI  while the other has remained silent on my suspicion of sockpuppetry . What do you think, is there enough behavioural evidence to go to WP:SPI?
