Why would you delete your account? If you're a free member, (as I am) it's erm, free. What I get out of 1x is a portfolio gallery of curated images rather than say flicker or 500px where any random shot can be posted and shared. Having looked at your page on 1x it shows a range of superb quality images that look really good and cohesive. Why lose that? That's probably due in no small part to the shots being curated and suiting 1x's gallery style. But I notice you don't keep any non-published images? That's a shame because non-curated images are often just as stunning. If you want to promote yourself, then all you need to do is to direct your clients to this page alone. Apart from that, I also get paid from image sales and occasionally a warm fuzzy feeling when something gets published!
Having said all that, if you want lots of 'likes' and a broad social media experience, then 1x certainly isn't for you. There's hardly any of that, and if you don't get an image published, then it's invisible. (Unless you direct people to your unpublished folio) A lot of people get frustrated at this and quickly leave in a huff. Published shots however do get a lot of views. But of course, only around 5% of shots submitted get published. That does mean their front page is usually of a very high standard and not filled with pictures of piano playing cats. So it's a double edged sword.
