Am using my phone to post pictures but the acc growing on different ip with proxy, but i think the problem is IG block my device ip mac because when i try to log in any account he give me this error '' sorry., there was a problem with your request ''Hmm. That has happened to me and it was due to my IP being banned by Instagram. Do you use any Bots or anything? If yes, do you use any proxies? It may be also due to the image you are posting. If it is an image which does not meet Instagram's policy. Try uploading the picture with another device.
