If you change your URL with the new tumblr update(that happened September 2015) be aware that any post you made as the old URL will stay as the old URL on all reblogs and not automatically change to your new URL. For example, if you post a gif as ilovechocolate and change your URL to ilovevanilla… that gif’s username will stay ilovechocolate on all the reblogs done before the URL change, which means if they want to find that gif maker… they can’t just click on the URL because it will bring you to the blog ilovechocolate and not your new one ilovevanilla

So…. that means if someone changes their URL and doesn’t save the old one and someone takes your old one… all the reblogs of your original posts done before your URL change are gonna link to that person’s blog and look like they posted it

ARE YOU KIDDING ME staff!?!?!?!
