Hi folks, I recently posted the information below into the community I help to moderate. Please feel free to re-use this if you'd find it useful in your communities:
Why was your post deleted? A moderator's perspective
As moderators, we're sometimes asked why posts are deleted. If this has happened to you, please read on to find out more.
One of our main purposes as moderators is to make sure that this community has value to its members, and a big part of that is to discourage spam and encourage the sharing of genuinely useful content.
Like any other online community, we get a lot of spam posted here - For every post that you see here, we've probably removed 2-3 spam posts. Because of the quantity of spam, this means we have a very low tolerance for things that could be spam; so, how do we decide what to let through and what to delete?
The spam warning box
What it is: Google does a pretty good job of alerting us to spam. In the picture below, you'll see the red, 'spam warning' box (only visible to moderators). Google tracks people's activities on G+ and if they post duplicate content, post too quickly or have been reported as a spammer elsewhere, then the chances are that their post will have this box. If I see the red box on a post, I will delete that post 95% of the time. (Please note, I am not picking on the person shown in the picture, it was just the first of many red boxes that I grabbed this morning!)
How to avoid it: Simply, don't get a reputation as a spammer. In other words: post good content that others comment on and share and don't post duplicate content or post too quickly to many places. The red spam box is the first thing we'll look for and the first posts we'll remove.
Posting in the wrong category
What it is: Most of the time, I will delete a post if it's in the 'Public Post - Uncategorized' area. We don't think it's too much effort to put your posts in the right place, and if people post in that category, it looks like they haven't read our posting guidelines or taken the trouble to learn how our community works and find the right topic for them.
How to avoid it: Simple - Categorize your posts properly.
Not adding value
What it is: We will often delete posts that don't add much value to the community; these could be things like: motivational quotes, large images without much text, links without an introduction or context, make money or get rich schemes, affiliate networks and lots of others. Again, we have a pretty low tolerance for this sort of thing.
How to avoid it: Make sure your post adds something to the community. Does your post inform, inspire, educate or entertain? Will it promote discussion? Does it share your personal perspective? Is it original? Is it something our members will find useful ? If you can answer 'Yes' to one or more of these questions, your post will live and thrive.
In short, to avoid post deletion:
1. Don't spam or get a reputation as a spammer
2. Post in the right categories
3. Share interesting, engaging content
4. Read our posting and community guidelines
Thanks for listening,
