A single X post holds 280 characters. Write more than that and Ocoya splits the post into a thread automatically rather than rejecting it.While composing, Ocoya warns you before you schedule:
Twitter caption exceeds 280 characters and will be split into a thread
The hard limit is 5,000 characters. Beyond that the post is refused and you’ll need to shorten it.
Threads, Bluesky and Mastodon behave the same way, each with their own per-post limit: Threads 500, Bluesky 300, Mastodon 500.
X rejects posts that are identical to something you posted recently. This is X’s own anti-spam rule and applies whether you post through Ocoya or directly.If you need to repeat a message, change the wording, swap the image, or leave more time between posts.
“My post became a thread and I didn’t want that.” It was over 280 characters. Shorten it to a single post.“X keeps asking me to reconnect.” X expires access periodically. See Reconnect a channel.“I connected a second account but it replaced the first.” Your browser was still signed in to the first account. Sign out of X, then connect again.
