so i got a packages of 51 profile links to build. it took me 2.5 hours and only 29 of them where actually working. however i also found that most of the forums/profiles are based on the same platform for example phpbb so it even makes it easy to search for this on google, and maybe someday someone will find how to automate all this process (i dont mind to enter captchas though.. ) one year ago i started with the profiles links and it worked for me pretty good. ofcourse i dont do only this kind of link building, but still if you looking for new options its a great deal. anyway if you have the time you can download my updated list
