If the case is SE penalties for the only fact of buying links, you may be penalized also for paid links in authority sites.
Right now entrepeneur.com is selling links.
What about a new PR0 linking from this website?
Not in the casino field but I now about sites ranking very well with something like 200 links from a trade/links company.
If I decide to use one of these companies, adding links at the path of 5-10 per month I can’t see the risk.
