A format that survives moderation, and the week of groundwork that earns it.
The format that survives moderation is not a launch announcement. It is a story about the problem, with the product mentioned late.
Ten useful replies in the sub before you post anything of your own. Mods and regulars both notice.
Post the outcome you got and how, not the launch you did. The tool belongs at the end or in a comment.
Titles with links read as promotion and get removed on sight in most subs.
Politely, once, asking what the issue was. Never repost. Reposting after removal is what gets accounts banned.
