If you are just going to link and not to quote then you can do that in the source block as suggested.
If you are going to quote ( or copy the text in sone way ) then personally, I feel that you should acknowledge the author (s) If it has essentially been written by one person (check the changes tag) .You could use something like
Jo Smith, profile of Fred Bloggs 1850-1950, Wiki-tree profile Bloggs-22 , accessed 1 Oct 2017 followed by the link
If many have worked on the profile then you could put the author as 'multiple contributors or editors '
Edit, just checked your example. In this case the initial creator left an unsourced profile, ackowledged at the bottom of the profile. The bio was written and sourced by another person.
Your citation could additionally include mention of the original gedcom ie add ...Bloggs-22, ( A Bloggs , gedcom Bloggs family 2011)
