The timeout appears to have been increased from 35 days to 42 days, and the conversion to bots always happens on Monday, so the actual period could be 42-48 days. The latest botification was done to teams that had last logged in from March 24 to March 31.
Last season, the limit was $6000, but somewhat less for 18 and 19 YO. This season, I haven't found any players that have been transfer listed, including some over $6000.
