There is a reason given: Abusing multiple accounts
You're already blocked on Magic love, now that account is blocked too as it is a sockpuppet and the original block extended for attempting to circumvent over it.
Currently we're in the middle of deciding how they will be promoted; I can't give you a clear answer right now sorry, but this page should tell you roughly what.
Jiawheinalt, the #time parser always shows the current time. That's why when using a custom signature, you have to substitute it in. Else, per your example page above, signatures would always show the current time or the time the page was last edited by any user.
This is why the signatures of users like Ozank and Monchoman45 use {{subst:#time:H:i, M j, Y}}.
Erm... those magic words don't exist in MediaWiki - and even if they did, it would still have the same issue. The REVISION magic words show the date of the latest edit by any user. You'd still have to subst: them to fix the time/date.
