I think this would block you from visiting the websites, but they'd still show up on search results. uBlacklist doesn't block them, but rather just hides them for search engines which IMO is a better approach.

Yeah, I just tested this, and you're right. Going to google.com and entering solveyourtech as a search term, did indeed still return their site as a result.

On clicking it, uBlock blocked my visit, but that may or may be not enough for you, in which case an additional plugin may be warranted.
