How many links on each web 2.0 property?

2 links On each Web 2.0 1 link on main keyword and other one is LSI Keywords And Use 3 to 4 keyword 1 main And LSI Keywords.

Since I use free web2.0s and don't want them to be deleted, I build wordpress + blogger blogs then get ~5 articles on them and drip feed them.
For links, I put my links on the 2-4th article and also include another link to another site to not get banned for "seo purposes". I've had a few blogs deleted for that reason before I tried this.

You can use maximum 2 links.
