It is very easy to misuse Flickr and annoy other community members or even get your account deleted!

Here is a list of NO-NOs:

• Not taking and posting good quality photos: the main idea of making it big is to contribute with valuable content. It all starts from here.
• Not organizng your photos properly: spend a late afternoon from time to time and add some coherence to your photostream. Remove irrelevant pictures, create several sets and add your photos to them. Help me have a pleasant experience when visiting your stream.
• Spamming other people’s photos with comments: if you want to promote yourself, do it subtly. Don’t post “in-your-face” self-promotion messages. Shameless promotion is usually frowned upon on Flickr.
• Adding your photo to too many groups: it has been often said that Flickr penalizes members who add their photos to tens of groups. What you may want to do instead is to add it to five or six groups at first, then remove it from some of them before you post it to others. This way, you don’t break the unwritten rules and you get to see your photo on the front page of many groups!
• Putting irrelevant tags on your photos: again, users who are desperately to get their photos viewed many times will think it’s a smart idea to stuff tens, if not hundreds of tags that often have nothing to do with the image. Not a very bright idea. Why do it, when in you can add a wealth of tags without being irrelevant! So make sure your tags really represent your picture.
• Adding too many similar photos instead of selecting the best one for display: You should always keep your stream clean and relevant. Decide on one photo in a series and display that one. It’s more about quality than quantity: hand-picking your best shots and keeping a highly curated gallery will pay off in the long run.
• Not interacting with other people, but expecting masses of people to come and praise your photos. It’s all about a community spirit. Take the time and appreciate other people’s work. Add their photos as favorites, give them praise or constructive criticism. Think about it: if everybody refused to do these things, the community would be dead. It is small actions like these that make Flickr so dynamic.
• Not having a good profile page: as I explained before, your profile page needs to contain more than a bunch of things about you. It is your opportunity to “sell yourself” and attract people’s admiration. Don’t waste it.
• Not having a good-looking, unique avatar: your avatar is your way of “branding” yourself. And, as any experienced marketer will tell you, a good idea is to make it unique and memorable. A picture is worth a thousand words – yes, even a small one. It is what represents you throughout the community, it is the first visual element that people come in contact with when interacting with you. Try to avoid cliches and come up with something catchy that will really make an impact.
• Not putting enough effort into taking care of your photostream: you should really devote some time to doing the small things that make a difference. These include tagging and geotagging some of the photos properly, arranging them into sets and collections, adding them to groups, interacting with other people…and all the other things mentioned on this website.

Voila. Here’s my list, and I’m sure it’s far from exhaustive. What would you advise someone not to do on Flickr?
