Started getting rid of spam

So for the longest time I have been wanting to get rid of spam followers. Today I just happened to decide that I would look through and see if I could find some and block them. I managed to find a wellness coaching company, a wheelchair company, an interior design company, and various others. I fear one day I may regret blocking that wellness coaching company and quite possibly the interior design company as well as you never know when you will need them. I was just looking for companies and things that really appeared to be spam so pretty much if you had a picture and a name that seemed legit I didn't block you. I thought about the ones that clearly appear to have not been active for over 6 months but have decided not to block them right now. I'm having second thoughts about the wellness coaching company.
