The site mods have other things to do. example: Taking care of their own family.
The site mods themselves are barely active because they have other things to do, so therefor they are usually burnt out before they can do things. Site Mods come here to approve and disapprove. Some are online and some are not. it's a perfect and sometimes not perfect balance between when they are and are not online.
MSMG only does that because they mostly give no shits. they target those who beg and those who feel down, it happened to me twice. Another reason is that they find annoying the site mods fun, because they know the Site Mods won't actually care.
