Using Twitter, Facebook and Instagram for business

I have set up Twitter, Facebook and Instagram accounts for my company. I have installed both ‘image-blocking’ and ‘advert-blocking’ software on my internet browser that blocks all images and adverts which may appear on any site – but specifically for Twitter, Facebook, etc. Furthermore, my Twitter and Facebook accounts are linked – meaning that whatever I post on one site, will automatically appear on the other. I can do this for Instagram as well. Hence, my interaction with these sites will be kept to the minimum. I have set up these social media accounts for general marketing purposes and interacting with customers, etc. As the business is an online one with probably all the customers being international, this manner of interaction/advertising is probably most suitable for the technological nature of the company. In light of these precautions, can I make use of Twitter, Facebook and Instagram for this express, business purpose?
