I understand your point zingo, and I've sent you a PM already about that.
Let me point out a few facts regarding this issue:
1) I've mentioned some parts of the service in the OP already, but to go closer to what's behind it, imagine links that are mentioned in public indexed chats / discussion groups / social interaction / shares / likes / tweets. The focus is on links which are supposed to be shared between a group of people interacting on social networks / social platforms. As the links are thrown in into a chat for example, they aren't considered spammy as people tend just to post links about a topic in many cases without the intention of purely linkbuilding. That's for avoiding duplicate content issue as well as no written content is used here.
2) I won't mention any platforms / sites / names / whatever for the following reason:
I guess most guys here remember
TRAC tickets - They were used by one guy first on the forum here (at least from what I know), then got copied by one guy who spammed about 80% public available TRAC sites with each order he had. RIP.
Moodle - a small group of guys used it until the copycats found out and copied. RIP.
EZine - everybody used it and copied from each other about interlinking.RIP.
Dochosts - one service brought in dochosts as the very first provider here on WF. Copycats raped it, dochosts getting more and more useless. You gotta think twice how to find new solutions for dochosts, bet you know what I mean Grind! RIP for dochosting.
Wikis - long time ago not that many spammers on the platforms, getting devalued more and more.
3) I explained what kind of links are used. I think considering it's fine for guys to use 'secret sauce' in every service it's kind of unfair not to accept my explanation about this service. I could have gone like selling Web 2.0 properties with secret sauce and have no problems - but wasn't my intention, although it had been smarter I guess.
If anybody has more questions, feel free to ping me up.
