We have an old portal (version 2.2.2), which was a long time without updating and without configuration of captcha, allowing user registrations by spammers.
Analyzing the tables, I noticed that a particular table has several records (3327083 table rows) and consumes about 197MB.
Is there any way to make sure all the records in this table are real and not created by spammers?
