I would call InstaPlus a great way for beginners to promote themselves online (for people like me, "retirees"). Everything is extremely simple and clear; the service automatically follows other accounts, likes, and comments on photos. By the way, in my opinion, it imitates real communication quite well – you can't tell the difference from a real person)). Plus, there are 5 days of free service, which is also quite significant and very important...
