No, it does not. When you follow someone, they will receive a message informing them that you have done so. If you use your main Instagram account, there is no way to follow someone without them seeing a notice. However, if you use the Facebook-owned service, followed users cannot see your follower list.
Instagram, like Twitter, allows anybody to follow anyone else's photo feed, including yours, unless their accounts are set to "private." Let's imagine, though, that a few individuals followed your Instagram photographs before you made your account private. There will be no more sneaking a peek at your Instagram images for them. They will know everything there is to see even if you don't want them to.
The people who have been following you won't be able to access your photos anymore unless they work at Instagram or one of its partners. However, that doesn't mean that they can't tell other people about the account. Maybe they'll even help them find pictures of animals in unusual positions.
You should use common sense when letting people follow you on social media platforms. If you don't want everybody to know what you're up to, make sure not to include any information in your profile that would identify you. For example, you shouldn't post pictures of yourself with your face visible throughout the site. This is just common sense since only you know what's going on with your mind and heart. If you do post such things, others may question your reasons for doing so.
In conclusion, strangers following you on Instagram isn't dangerous per se, but it can lead to unwanted exposure. Use common sense and don't include sensitive information when allowing people to follow you.
Tap the "Following" button at the top of the screen from their profile. You'll see a list of every person they're following here. Enter your own name or Instagram handle in the search field. If your name appears, that signifies they're interested in you.
If they haven't recently started following someone, then they may be blocked by the follower/followed relationship setting. Make sure to take any complaints about blocking issues down to the ground if you want to keep seeing updates from them.
When you unfollow someone, they will not be alerted. Please keep in mind that if your account is set to private, you can delete persons from your following list. You can also prevent them from accessing your computer. However, if you do so, they cannot follow you either.
There is no method to follow someone anonymously on Facebook since the person you're following will always be able to see your profile and name if someone establishes a bogus account with a bogus name and wishes to follow you. Because there is no way to verify who they truly are, they are, in a sense, nameless. However, if you have privacy settings set properly, then no one should be able to see your activity unless you give them permission.
At the time of writing, Facebook does not officially enable you to follow someone without their knowledge. Whether you choose to give him a friend request or follow his updates, you will be aware of what has occurred. However, many users have reported being able to do so using browser extensions.
The following on Twitter is not reciprocal. Someone who finds you fascinating can follow you, and you are not required to approve or follow them back. Protect your tweets if you want to control who follows them.
