Social media platforms limit how often you can post to prevent spam and abuse. The exact limits and recommended posting frequencies vary by platform:

• On Facebook, brands are generally recommended to post about 3 times per week for optimal engagement, with some suggesting 1-2 posts per day. If you post excessively and see the message "We limit how often you can post," it means you've hit a temporary restriction that could last hours or days to curb spammy behavior. You should wait, avoid rapid posting or commenting, and consider appealing the restriction if it persists.

• Instagram suggests posting 3-5 times per week for feed posts and 2-3 Stories per day. If you exceed Instagram's limits or exhibit suspicious activity, you may get temporarily blocked from posting. Repeated violations can lead to account bans lasting days.

• Twitter (X) allows for higher frequency, recommending 3-7 tweets per day due to the fast-paced feed.

• Overall, many platforms recommend posting consistently but not overly frequently to maintain engagement without triggering limits.

In summary, posting limits exist to protect communities from spam. The best approach is to follow platform-specific recommended frequencies—generally a few posts per week to a couple per day depending on the platform—and avoid rapid or excessive posting, which will provoke restrictions that are usually temporary.
