1) Prior to Telkoms new ADSL offerings in February I am not aware of anyone being throttled or shaped by TI on uncapped accounts according to the GBs they used, however many line and other faults were attributed to this.
2) In February only the capped accounts were supposed to be soft-capped, however some uncapped users were informed they were soft-capped by the TI tracker and suffered a degraded service. After much bitching here on MyBB the TI Tracker no longer functions on uncapped accounts and speeds returned to normal
before February month end.
3) Since the beginning of March TI Tracker still does not function on uncapped accounts (use
http://userstats.adsl.saix.net/ instead) and no confirmed reports of TI soft-capping have been posted.
My gut feel is that soft-capping on capped accounts was not implemented properly by the dev team responsible and the situation was made worse by comments from the infamous TI help desk reps who really did not know what was happening and were trying to get irate users off their backs.
Only time (and maybe
ranger 
) will reveal the future of soft-capping on uncapped accounts.
