You do need to realize that the Ask moderators can't keep track of everyone's answers; as there are many. That is why you should help them by reporting the ones that have profanity included in them. Another thing that you need to know is that whoever you argue with might just end up reporting you in order to save themselves from being reported.
Vulgar language is not allowed on ASK if you are seeing it in other people's content it should be reported as it means it was missed by filters. We do rely on our users to report content that is against the Community Guidelines as well as system filters and tools to pick this sort of thing up. Thanks :)
Although it may seem like it, I highly doubt they are targeting you unless you have done something extra bad and gotten their attention. I haven't seen a lot of profanity on here. I have seen people do things like substituting an $ for an S in certain words so it won't hit the filters.
