I haven't actually encountered any submission spam so far. Glad something is in the works for comments.
Text surrounded by asterisks (*) is italicized.
Text surrounded by plus signs (+) is bolded.
Text surrounded by vertical bars (|) is quoted. If you double-click a paragraph, it will be quoted.
Text surrounded by tildes (~) is blocked out.
Symbols such as *, +, |, and ~ can be used literally by placed a \ in front of the text.
A user's name surrounded by at signs (@) links to their profile, and the user is notified that you mentioned them.
A word surrounded by hash signs (#) becomes a tag and links to posts with that tag.
Text after a blank line that is indented by two or more spaces is reproduced verbatim in a different font.
URLs become links. However, new users cannot post links in comments.
Hubski URLS become embedded cards, displaying information about the post or comment.
Text can link to URLs by using the following format: [linked text](http://theurl.com)
Youtube, Vimeo, Soundcloud, Twitter, and Spotify urls will embed the content automatically.
Image URLs (.png, .tif, .gif, and .jpg) will embed automatically.
If you follow a few topics like #technology, you'll see it pretty regularly.
Makes sense. I think what got me with this was the huge impact on usability. A single comment almost made me back out from the rest of the comments due to sheer length.
I think what's needed is for the site to autoblock comments that contain html or something. mk
I agree. 90% of comment spam is straight up HTML BS.
If you filter #spam a lot of times the post will be tagged as an add-on tag which seems to filter it out of most people's feeds.
