Hi @IJBSRR_Journal,
First, take a good backup!
For a list this long, I would not recommend attempting to go through the list manually. I would recommend going to the database directly (e.g. using phpMyAdmin) and looking at commonalities in spam users. For example, I see lots of domains like rediffmail.com and yandex.ru. There are probably thousands of users with these domains.
Get the user IDs of all matching users…
SELECT user_id FROM users WHERE email LIKE '%@yandex.ru';
…then, on the command line, use tools/mergeUsers.php to get rid of those accounts in batches.
See e.g. this thread for more ideas.
