All time since September 1993. One of the seasonal rhythms of the Usenet used to be the annual September influx of clueless newbies who, lacking any sense of netiquette, made a general nuisance of themselves. This coincided with people starting college, getting their first internet accounts, and plunging in without bothering to learn what was acceptable. These relatively small drafts of newbies could be assimilated within a few months. But in September 1993, AOL users became able to post to Usenet, nearly overwhelming the old-timers' capacity to acculturate them; to those who nostalgically recall the period before, this triggered an inexorable decline in the quality of discussions on newsgroups.
By this definition I never experienced a non-degraded internet, since my family didn't get a computer capable of internet access until 1995.
Edit: then later on google groups allowing you to post on Usenet dealt what was probably its killing stroke, having already long been on life support due to all the spam posted to unmoderated groups making them all but useless.
