If you're asking about the condition of spark plugs, your images must of the firing end of the plug, close up, in focus and well lit or it will be deleted. Posts with distant,, blurry, poorly lit images will be deleted. This is especially important if you're seeking advice on spark plugs, brake rotors, electrical connectors, etc., where image clarity is critical to helping you.

What the written rules don't show
- Unpublished minimums. Many communities remove posts from new or low-karma accounts through AutoModerator settings that are not on the rules page, often before a moderator sees them.
- Reddit's own filters. Reddit's site-wide spam filters can remove posts from accounts that mostly share links to their own site, in any community.
- The community's norms. Many communities see themselves as peers, not an audience: post where you already take part, and make the post worth reading without the link.
Let your AI read the rules before it posts.
