Stubbornness Some users cannot come to agreement with others who are willing to talk to them about an editing issue, and repeatedly make changes opposed by everyone else. This is regrettable—you may wish to see our dispute resolution pages to get help. Repeated deletion or addition of material may violate the three-revert rule, but this is not "vandalism" and should not be dealt with as such. See also Tendentious editing 

Also can you refrain from calling anyone a vandal or try indicating they are vandalising without proof
thank you
