IG questions

So I started a little IG journey. Here are my questions:

1. I used Gramblr for uploading pictures from my PC and I've read that my account can get banned because of it. Is this true?

2. How many accounts can I run with a single IP?

3. IG says I must not use my website name as a name of IG profile. OK but I can use everything else, right?

1. It's against Instagram's ToS to use third party software to automate tasks. But you will be fine as long as you're not using too aggressive settings and as long as the program isn't detected by IG. I've heard many used Gramblr without any issues.

2. Thousands. Recommended is 3 accounts per IP, go above that and you most likely will run into more PV and password resets or even permanent suspensions.

3. Yea you can name it whatever you want.
