Okay, so since I don't completely understand your question, I'll just try my best to explain each of them.
1. Someone can find your location based on a photo that you posted; If you tagged the location, obviously they can find the location. If you put in the caption where you were when you took the photo, again yes, they would be able to find the location. If you were in a well known location when you took the picture and you can clearly see the background or the setting, with context clues you can figure it out, but as far as the social media platform telling the public where the picture was taken or posted, it is not authorized to give out the location.
2. Colleges use social media during the admission process; Some colleges do check the social media, not all but some. Mostly the platforms where you are most careless, so watch out. You can decide if you want your account to be public or private in the account settings.
3. items posted online can be removed at anytime; yes it can be removed, but depending on how popular the post was, people will still remember it.
4. Things you post online become public information; yes and no. On any and all social media platforms, there is a setting where you can choose the audiences the post reaches. There is the public setting where it's completely public and out into the world, there is the privacy setting where you are the only one who can view it, there is the friends setting where your friends can view your posts, and on some there are the friends/followers except... where you can choose specific people that can't view your post/s, and finally there is the specific friends that can view the post. You can also decide if you want your account in general to be public or private, which you can go into the settings and decide.
5. Employers screen job candidates based on social medias; like number 2 up there, some employers do check your social medias, but if you have you account settings as private they will have to request access.
I hope I helped at least a little! If I didn't i'm sorry i didn't completely understand the question so I tried my best. If I did help, I'd appreciate it if you would give me brainliest! Thank you!
