Read and document each subreddit's rules

Reading and genuinely documenting each target subreddit's actual rules addresses a real, significant risk that's easy to underestimate — Reddit communities maintain genuinely distinct, often strict rules about self-promotion specifically, and violating these rules, even unknowingly, typically results in real bans that permanently end your ability to participate in that specific community.

The genuine assumption that rules are broadly similar across different subreddits represents a real, costly mistake worth explicitly avoiding — each community genuinely sets its own distinct rules, and what's permitted in one subreddit may be strictly prohibited in another superficially similar one, making individual, careful review of each target community's actual specific rules essential rather than optional.

The self-promotion policy specifically deserves particular documentation attention, since this varies dramatically across communities — some subreddits permit modest self-promotion under specific conditions, while others prohibit it entirely regardless of context, and understanding this specific variation for each of your ten target communities shapes what kind of activity is actually viable within each one.

This documentation work, while requiring genuine time investment before any active posting begins, prevents the real, often permanent cost of an early rule violation — a ban resulting from ignorance of a specific community's rules eliminates your ability to participate in that community entirely, making this upfront research genuinely cheaper than the alternative risk.
