technichally shold not be bad to allow to hide long time ago references.
But people that proposed it sayd «for people that are on CS since more than two years, have many refernces, are VERIFIED" should be possible to hide references mote than 2 years old, as long remain visible at least 100 references.»
would be that paying for ferificanion would allow to use this feature ?
(incidentally it is a double edge sword: every verified person would be under the suspect to have used that feature !)
