Ah, ok: the argument is that HN members will be mentioning "spring" with increasing frequency during the matching season of time? To answer then, no. The data is not cleansed for those purposes, so discount the Spring data as you will. FWIW, a regular expression match for season returns 1940 results across the entire HN dataset, which spans 49 months, meaning that the number of context independent mentions of that word are ~40 month.
