Question about linkpusihing

I was thinking of doing some modest linkpushing. Write 6 articles each with the same keyword linking to my moneysite and publish these
on respectable article sites such articlesfactory and amazines.

Then buy some packages to build hundreds social media links to my published articles. One question is:
should the keyword links from the social media sites linking to the articles be the same as the keyword
I use in the published articles?

Second question: do I run the risk of penalizing my moneysite in this way or am I safe doing this?

Thanks!!
