New report reason: Username similar to link text

It would help catch more spam

Describe the solution you'd like

SD should report posts where the text of a link is similar to a user's name, as that is almost always a sign of spam.
Post example (Username: Cool Spam Service, imagine the link went to a spam site instead of SO):

Your problem can be solved easily Cool Spam Service with recursion...

We would want to catch these and give them a higher score. This is different from URL similar to username, as some companies' website doesn't always include their username (MS example)

Looking at findspam.py, there's this function that contains some code that could be used to extract link text from a post. Specifically, this line finds link text within the string s.

links = regex.compile(r'nofollow(?: noreferrer)?">([^<]*)(?=</a>)', regex.UNICODE).findall(s)

I.e.,

>>> import regex
>>> s = '<a href="google.com" rel="nofollow">Test</a>'
>>> links = regex.compile(r'nofollow(?: noreferrer)?">([^<]*)(?=</a>)', regex.UNICODE).findall(s)
>>> links
['Test']

There's another function here that seems to check similarity, and that's used in the "username similar to website" rule. Lastly, there's also a wiki page on adding spam checks/rules.

If this is something that's a good idea to add, I can take an attempt at making a PR implementing this change.
