LinkedIn give you up to 50 groups to interact as a member, places where you can raise your voice to express your opinion, exchange ideas with colleges, create jobs, promote your services, etc. Each group has their own rules, so, check before you post your article, or comment. If you don't follow the rules of the group, you can be removed from it, or your article/comment can be flagged as inappropriate. Also, be sure to post under the correct category, there are three of them: Discussions, Promotions, and Jobs. Also, your post can be flagged using 3 different flag categories: Promotion, Job, and Inappropriate.

Take a deep breath because we are going deeper into the LinkedIn flag system, and how it works...

There is a misconception of an 'OPEN' Group. There are 2 different type of groups: Members-Only and Open Groups. Linkedin is clear about the differences between them: "Members-only group discussions can only be seen by other group members. Open group discussions can be seen by anyone on the web and can be shared on other social networking platforms." Check the following link for more details:

Members of the group don't moderate the group, that's the responsibility of the LinkedIn Group Owner and managers. The only way that members can be moderators is when the Group Owner or a manager assign the moderator or manager role to another member of the group. How? One of the managers or the owner of the group have to proceed in this way:

1) Move your cursor over Interests at the top of your homepage and select Groups.
2) Click the group's name.
3) Click the Manage tab.
4) Click Participants on the left and then click the Members tab.
5) Under the member's name, click the Change Role link and then select To Moderator or To Manager.

Let's proceed with one example...

One of your contributions is flagged by the member 'X'. The owner of the group will receive a notification on the group's dashboard. (Image below) So, it's up to the owner of the group or one of the managers to flag your contribution or not. Also, check the red mark with the number 2... The Group Owner and managers know who flagged the contribution.


Now you know how the whole flag system works in the other side. Some managers and Group Owners hide behind this process to censor members. They usually pass the responsibility to LinkedIn, but in fact, they are the ones playing with the member contributions. They can veto you if you don't share their same ideas. So, be careful and analyse the group that you are planning to be a member. Before you contribute to the group, ask the manager or owner if the group is FREE of censorship, and ask how they are treating a flagged contribution. If the answer doesn't convince you, leave the group.
