This is assuming it actually attracts those views instead of attracting false flags of those views. One subreddit I've seen which seems to allow decent political discussion regardless of side has come under attack because they don't censor certain positions. The attacks are done by very blatant new accounts spamming extremely offensive content in an attempt to get the sub flagged. I've had the displeasure of encountering such posts on multiple occasions before mods were able to remove them. It would not be difficult for those posting such content to determine what is the most offensive thing that won't be removed and then focus on posting that content until either mods have to start censoring it or the subreddit becomes overran with that specific content. In the former case they just repeat until they are happy with the new standards on what are allowed. In the latter case the reputation changes and begins to attract people who are primarily interested in the flooding content, effectively ending the sub as being a place of open discussion. The mods are handling it for now, but that is likely to only be for as long as the flood of the targeted attack doesn't overwhelm them.
