1) Your first private message to a stranger on social media includes a link to join your opportunity.
2) You get angry replies via private messaging and/or you have been reported as a spammer.
3) You post links to your opportunity or website in the comments section of other people's social media posts.
4) You compulsively want to talk about your company or products, without anyone asking you to share.
Finally... this one is the most important one...
5) You engage in interactions online, with a hidden agenda, hoping to transition the topic to something that would get people interested in your opportunity, without caring about knowing the other person.
