1. I have seen users on Facebook posting their links in 20 - 100 Facebook groups per day. 2. Some users post their links on their own page and then share the link of that posts to 40 or more Facebook groups per day. Which technique is fair and safe enough so that accounts do not get banned? Please let me know and if you know something else that can be done on facebook for marketing and that is more safe and fair then please share that also. Sharing ideas, tips, and facts is the only way we can grow our knowledgebase.
