I just saw this answerer https://webmasters.stackexchange.com/a/27574/10527 had originally posted under the name "phpbb3rocks" the question was phpbb3 related
Now on this joomla related post he changed his name to ilovejoomla https://webmasters.stackexchange.com/a/27575/10527
They are new to the site, not sure what they're trying to do by changing their name every time they answer maybe increase their chance of an accepted answer? Not a big deal IMO unless they try and start spamming links, just wanted to point it out
