Can we ban spam source sites?

There are so many of them using vote manipulation, posting old news. Here’s an example: https://np.reddit.com/r/CryptoCurrency/comments/cxi498/wikipedia_joins_brave_as_a_verified_publisher/ The user’s post history is entirely cryptoverze.com spam. Here’s another: https://np.reddit.com/r/CryptoCurrency/comments/cxhm4g/in_terms_of_riskadjusted_return_bitcoin_eclipses/ Both on the front page right now. submitted by /u/mmmmmmm7 [link] [comments]
