Q: Suspicious behavior between two MSE users

NorbertIn fact the purpose of this post is flagging one suspicious behavior between two MSE users. But I'll start from something seemingly non related. In the question Downvoting complete solution there was a discussion of downvotes for the question and answers in the thread Calculate the n-th term $1,...

Q: Congratulations, Arturo!

user940I think congratulations are due to Arturo Magidin on hitting 100k reputation points here on MSE! All the users of this site are better off for his tireless contributions, and we appreciate his positive influence on mathematics and mathematics education via this site.

discussion specific-user celebration
Several of the first posts with this tag are congratulatory posts.
On MathOverflow, I might be the user responsible for creating this tag no meta: data.stackexchange.com/meta.mathoverflow/query/1105163/… I have added it to a rather famous question about a user who left MO.

Q: Conjecture about rational numbers

Mister.ExpandeadInspired by normal numbers I created the simple following problem: First take a rational number, for example $\frac{3}{4}$ which is equal to $0.75$; now add the first digit after the decimal separator to the digit $4$ we get $\frac{3}{4.7}$ which is equal $0.63829\cdots$. Now take the second digi...

Normal number
In mathematics, a real number is said to be simply normal in an integer base b if its infinite sequence of digits is distributed uniformly in the sense that each of the b digit values has the same natural density 1/b. A number is said to be normal in base b if, for every positive integer n, all possible strings n digits long have density b−n. Intuitively, a number being simply normal means that no digit occurs more frequently than any other. If a number is normal, no finite combination of digits of a given length occurs more frequently than any other combination of the same length. A normal number...
The tag called normal-numbers was definitely created before:

new-tag deleted-tag The tag normal-numbers was created twice in January, in both cases it was removed on the same day: https://math.stackexchange.com/posts/3509455/revisions https://math.stackexchange.com/posts/3513257/revisions
I did not find older occurrences of normal-number through SEDE.
