You can't bump a 2 year old thread. Commenting on a thread that no one has posted on for at least a month is considered a necro.
Necro Posting Verbal warning - 1 day mute - 3 day mute - 1d day temp ban Necro posting or “Grave digging” is the offense of bumping or replying to a thread that is over 30 days old. There are some exceptions however. These include help, ban appeals, introductions, reports, news and announcements, mod application, or suggestions. However, since this has been accepted, I am going to close it.
