New to instagram – a few questions

Hi there

Im just getting into instagram today…..never tried it before

I have a cpl questions after reading/watching a few things online in regards to using instagram for IM purposes:

1) when im starting to 'follow' other ppl – how many MAXIMUM should i follow a day so that my accounts wont get deleted?

2) i see that you can set up a 'business profile' – is this beneficial, or should i just keep it to a personal account ? (with the website & info listed inthe profile)?
