reddit: posting link: removed?

hello,

i want to post 10 posts day on my own subreddit.

but every time i make a post with a bitly.com link in it, the post gets removed.

how can i avoid this?

if i make a post without a link, it doesnt get deleted, even if i edit that post and add a link, doesnt matter what url/domain i post, it gets removed?

domain banned , you can try twitter.com

Maybe they dont allow url shortners
