For a start I suggest to investigate what caused the closure of these services.
The reason is not that instagram bots are not allowed and IG are banned all that sites. No. Reason is in rights that Instagram have on words "Insta" and "Gram".
Instargram are getting requests to block copyright violation and many services based in USA and who have this words in their company's names will be blocked in soon.
Instanobel.com - is not based in USA company and our company's name is "Engineering Company Nobel LLC".
So we are safety for this problems like Instagress or mass planner.
If some problems will shows for us, we will change domain name to another and will continue working.
Thanks for using Instanobel - the best bot for Instagram!
