What r/sysadmin is
A reddit dedicated to the profession of Computer System Administration.
IT software and infrastructure vendors whose staff can answer technical questions in public and say who they are.
Can a brand post in r/sysadmin?
The Advertising rule says Reddit's advertising system is there for promotion and tells vendors to buy a promoted post or sidebar ad. It also says vendors are free to discuss their product in the context of an existing discussion, and that users must disclose any affiliation. Posting articles from your own blog counts as a product, and content creators should refrain from directing the community to their own content. Accounts must be 24 hours old to post. In practice, a vendor can answer a thread where someone asks about a product category, say who they work for and add detail. They can't start a post to market a product.
What works
- Answering inside an existing thread where the product is relevant, with your affiliation stated
- Giving concrete, professional detail, which the Low Quality rule asks for
- Using your main account, as the account age rule asks
- Reading threads for the complaints IT staff raise about vendors, then fixing those in the product
What gets removed
- Starting a post whose purpose is to market a product
- Posting articles from your own blog, which the rules count as a product
- Undisclosed affiliation with a product you discuss
- Low-quality posts that add no detail, context or opinion
The rules, summarised
- 1. Account Age
Your account must be 24 hours old in order to post to this subreddit. Please use your main account to post or comment, or wait 24 hours and resubmit. If the issue is urgent, feel free to message the moderation team.
- 2. Professionalism
Please treat community members politely - even when you disagree. No personal attacks - debate issues, challenge sources - but don't make or take things personally.
- 3. Advertising
Vendors may discuss their product in the context of an existing discussion and must disclose affiliation. Posting from your own blog counts as promotion, and ads belong in Reddit's ad system.
- 4. Wrong Community
There are many reddit communities that exist that may be more catered to/dedicated your topic. Requests for assistance are expected to contain basic situational information.
- 5. Low Quality
Avoid low-quality posts. Make an effort to enrich the community where you can- provide details, context, opinions, etc. in your posts. Moronic Monday & Thickheaded Thursday are available for simple questions, or other requests that don't need their own full thread.
