r/civilengineering rules, stats, and what to post

This is a community for civil engineers and for people who want to become civil engineers. That is the whole pitch in the public description, and the rules back it up by pointing newcomers to read them before participating. The people posting here are working engineers, students, and folks aiming to enter the field. The rules also tell you a lot about the room. There is a strong safety streak, because the community bans DIY engineering advice to protect the public. There is a professional streak too, because exam talk, job posts, and job hunting all live inside weekly threads rather than the main feed. And the moderators state plainly that they remove posts which are disrespectful, promote self interests, ask for DIY advice, or ignore the weekly threads. Read that as a signal about what the community values, substance over promotion, and civility as a baseline.

For anyone doing marketing adjacent work here, one rule decides almost everything, and that is “No Self-Promotion/Blog Spam”. This community flat out does not allow self promotion or blog spam, so there is no soft version of this, no clever workaround, no sharing your own article because it is genuinely useful. The second rule that shapes posts is “No DIY Support”, which bans soliciting professional advice on DIY projects to protect public safety, so any content built around homeowners or hobbyists asking engineering questions is off the table. The third one is “No Complaints, PE/FE Exam, or Job Postings/Seeking Employment posts outside the weekly threads.”, which pushes a whole set of common topics into the weekly threads only. The remaining rules, “Participate Respectfully and Civilly” and “No Offensive or Hate Speech”, are basic conduct rules, but break them and you lose your standing in the community entirely.

Here is the honest read for a founder. This is not a community where you promote, so a good post is one that a working civil engineer would find useful with zero commercial angle. Share something from your own experience that teaches, like a lesson learned from a project, a clear explainer of a technical topic, or a question that invites engineers to share how they actually work. If you want to discuss hiring, exams, or vent about the industry, do it inside the weekly threads where the community expects those conversations. If your product touches civil engineering, the winning move is participation without promotion, answer questions well, be a real member, and let people discover what you do on their own. A good post here reads like it was written by someone who respects the profession.

The fastest way to get removed here is self promotion or blog spam in any form. Do not drop your own article, your product, your newsletter, or your company. The next trap is DIY content. If your post invites people to ask for engineering help on personal projects, it breaks the “No DIY Support” rule and it gets removed. Keep every complaint, PE or FE exam question, job posting, and job seeking post inside the weekly threads, because posting them as standalone threads violates rule 5. And of course, trolling, harassment, mockery, bullying, or any offensive or hateful content is out, since the community describes itself as inclusive and expects respect and civility from everyone.

What stands out to me is the “No DIY Support” rule and its reason, protecting the safety and wellbeing of the public, which tells you this room takes itself seriously. That is a good thing for marketers, because it means the people here are real practitioners who can smell a sales pitch from a mile away. There are no observed top posts for this community yet, so I would come in quiet, read the weekly threads, and let usefulness speak before I ever mention what I do. If you cannot post here without promoting something, that is a fine outcome, the trust you build is still worth it.
