Scammers for a fee can ban anyone you want and can for a larger fee get banned accounts back on line.  This is not good for those of us that think of IG as a stable platform.  It is NOT.  What it is , is a free platform owned and operated by Facebook and if this isn’t enough to get you thinking then nothing will.  I don’t as of yet know of an alternative.  I have over 2000 posts on IG.  If it went away tomorrow or I had to cancel IG and FB I would still be alive and doing photography.  That being said IG is a source of motivation, inspiration and entertainment.
