Requirements:

* 150 Mainspace edits
** First pass filter to narrow down query: user_editcount > 149
*** Second pass via independant query?
**** Screw that, way to slow. We'll use the API.
* Registered by: October 28th, 2018
** Easy. user_registration > 20181028000000
*** Done
* Not Blocked
** Probably fastest to do api queries? Maybe tie into generator query
*** Yes, Done, but via subquery
* At least one edit this year (Not for eligibility, but for mass messaging)
** Probably best to do on it's own query
*** Select rev_id from revision_userindex where rev_user = 123 and rev_timestamp > 20171028000000 LIMIT 1;
**** Nope, done via subquery.

Generator with block checking: select count(user_name) from user where user_editcount > 149 and user_registration < 20181028000000 and user_id not in (select ipb_user from ipblocks where ipb_user = user_id);
At present, returns 163,947 users.

+------------------+
| count(user_name) |
+------------------+
|           163947 |
+------------------+
1 row in set (16.19 sec)

Without block filtering, returns 181,301 users.

+------------------+
| count(user_name) |
+------------------+
|           181301 |
+------------------+
1 row in set (43.01 sec)

10/11/18 - Possible TODO: Pull lists from [[Category:All Wikipedia bots]], [[Category:Wikipedia alternative accounts]], and [[Category:Wikipedia doppelganger accounts]] . Discard these accounts for notifications. This would net about -6558 accounts - probably a bit less, as there is likely some overlap between those cats.
* Done!
