I have had a Flickr account for many years but seldom use it. Months, even years go by without activity. I'm not sure how to build traffic or if that is even possible or a goal. In short, I don't know what Flickr is for.
At one time, way back when it was free, I thought it might be a good place to set up albums for different types of photos - family, glamour, birds, artsy stuff, and so on. I had a few thousand photos uploaded. Then they introduced the pay version. I had to reduce the collection. I wouldn't mind paying if there was some use to it, but I don't think anybody ever visited my Flickr account and I couldn't identify a use.
I still have my account, but it is untended and a mess, so I won't give the link here for now.
I have two IG accounts and both accounts in the last couple of months got warnings about my use of the site. They seem to be very nervous over there! :( I wasn't doing anything wrong, and they never carried out the threats. (Just today IG auto-locked me out and then auto-released the lock two and a half hours later all with little explanation and unbeknownst to me except I read IG's emails later.) So it makes me think of getting a better place, and maybe it should be Flickr.
