We make bots, and we do run hundreds of accounts altogether to test the limits even at the same time all the test accounts are in a good state and working fine, we know what's going on, and whatever I shared is what I observed from people and different forums but own research doesn't end here. I still prefer normal proxies over expensive proxies because there is a reason we don't. We make different cloud-based software every month for different clients and at the current moment a lot of cloud-based solutions are knocked out due to login issue because they all use 3rd Party local Instagram API which is MPG25, MPG25 doesn't provide support for challenge required errors as they don't allow misuse of their API and same with Lavpasha Python API, and almost all services have login issues. It was too difficult for a day or two when it happened. Now with own research, we know what are the latest loopholes to get into Instagram using software without SMS code verification as a lot of panels has loop issue at the moment, they put the code and then again it ask them to add it again and it runs in a loop. Even we found a solution to login to those accounts for which API access has permanent blocked.
So, when you say as we don't know what is going on is totally useless since we do care about and will not public the current working method as if this loophole gets public, we will have problems with our panels and our services. We don't think as coders do, we think like a hacker who comes up with new different ideas every day and out of this world.
Currently, all our services are working fine with our settings in our panels and our settings on the software for our clients. So finally, boting is not dead and it cannot be. If PLAN A goes down, there are always other solutions which we have as PLAN B!
