I have discovered that the following two tags are too similar to each other:
riemann-zeta-function, with 299 questions tagged, has the description
The Riemann zeta function is the function of one complex variable $s$ defined by the series $\zeta(s) = \sum_{n \geq 1} \frac{1}{n^s}$ when $\o...
As you can see, in the latter case it was created by the user who was source of several problematic tag-wikis, as mentioned here: Recent suggested tag wiki edits.
