Is this cheating or disloyalty?

So my boyfriend got angry and upset because he noticed I was accepting random guys on instagram just requests, however I did not follow them back or message or anything just accepted. I didn’t think anything of it just thought of it as harmless until I was in his shoes and realised if he done that I’d be upset but he’s trying to say me doing that is not loyal behavior isit true?
