I built a no strings attatched intraday data API for r/algotrading and now they permaban anyone who links the API.For about 3 years, I was an active user in the r/algotrading sub, and built a free intraday api specifically to share with the sub.  I made a post showcasing it, and posted it.  It wasn't showing up in new like my usual posts did, so I deleted it and tried again.  Moments later, I was perma banned and the mods said I "carpet bombed the sub with self promotion"  I am baffled at this, considering I spent months developing something specifically for the sub.  It is a pure JSON Api with no monetization, search limit, or any account registration or anything.  It was a free api for the sub simple as that.I made a new account to try and be active again, and try again after some time without posting twice, months after the initial issue passed.  I immediately got banned the second I linked the api, claiming "we have issues with the publisher of this API".  This is pretty unreal that my API is banned from the sub, and posting about it will get you instantly perma banned.  I built it specifically for the sub, and they just ban anyone who links it now.
