One Reddit account posting to 20 subreddits daily will get flagged. Top agencies use 3-5 accounts per model with careful rotation. Here is how to do it safely.
Reddit rate-limits posting frequency per account. Posting more than 5-10 times per hour from a single account triggers anti-spam filters. Multiple accounts let you post to more subreddits without hitting these limits.
3-5 accounts is the sweet spot. Each account posts to a different group of subreddits. This spreads the activity and reduces the chance of any single account getting flagged.
New accounts need 7-14 days of genuine participation before any promotional posting. Comment on posts in your niche communities. Share non-promotional content. Build 100+ karma before posting to NSFW subs. Skipping this step is the most common reason for shadowbans.
Divide your 50+ target subreddits into groups of 10-15. Assign each group to one Reddit account. Rotate which account posts each day. Never post the same image from two different accounts to the same subreddit. Use a post scheduler to manage the rotation.
Every image posted from different accounts must be hash-unique. If Reddit detects the same image hash across multiple accounts, it links the accounts together and can ban all of them simultaneously. Spoof each version before posting.
