I just checked today and for one of my keywords, first 15 results are from my domain. It is not something I celebrate
there is another issue: it makes a site look spammy and may destroy its brand in the longer term. people hate being spammed with the same domain over and over - they want diversity and choice, pretty basic stuff.
as a webmaster, i definitely would assume black-hat tactics if i didn't know better.
