A lot of public places, schools, business block Reddit subreddits like WTF. If you just want to see images people post on Reddit a trick you can use would be to go to www.imgur.com/r/wtf which will allow you to see all images that get posted on Reddit’s WTF section. You can also try using a proxy, but that same filter that blocked you from Reddit in the first place may also block you from any proxy sites too. Another trick you can do is to view the Google cached page of Reddit as the cache is frequently replaced and constantly fresh. I have just tested the cache and it works under a current filter that’s blocking me. Just type reddit wtf or whatever subreddit in Google search and then click the Green down arrow next to Reddit top result and select Cached.
