BitHUmen:
If you are not attending one year at the site, then you get banned for inactivity. The account will permanently delete the ban after two years


fux0r:
Every night we run scripts to disable inactive accounts (that is, accounts where one does not use the web site for longer than 17 weeks in a row). They are disabled, and it is unlikely you will get them back without a good excuse. Donors and Power Users (or higher) are exempt from being automatically disabled for inactivity.
If being away for more than 16 weeks (4 months) is unavoidable, you must either become a power user (disabled after a year) or a higher userclass band (never disabled).


Majomparádé(majomparade.net)
With more than 8 weeks inactive, or more than 2 weeks ago registered, users under the minimum ratio of 0.6 with 1 GB download will be automatically deleted.


Pedro's
New accounts must be used to download at least 1GB and seed more than 1GB in the first 30 days of membership (not counting any start buffers). We want no spectators.
All users are expected to actively use the site. Accounts which will not download anything for longer periods of time will be eventually disabled. Again, we want no spectators.
Unparked accounts are disabled after 120 (Users, Senior Users, Uploaders Lite), 150 (Uploaders), or 220 days (Uploaders Elite, VIPs).
All parked accounts are disabled after a year (365 days).


SceneFZ
Accounts are deleted after 28 days from the last activity. Parked accounts are deleted 56 days after the last activity. Remember that regularly delete accounts with small ration.

BrokenStones
Unparked accounts are pruned when 180 days (for powerusers this is 1 year) have elapsed since the last recorded activity. Parked accounts are pruned when 360 days have elapsed since the last recorded activity. Also note that we regularly clean out accounts with very low share ratios.
Accounts with nothing uploaded/ downloaded after 4 weeks and are inactive for a week are pruned.


TheConnection.eu
Inactivity is something we want to discourage at TehConnection. As such we have rules which can affect your account if you choose not to make use of the site. The following account classes are subject to our inactivity rules:

User
Member

Accounts will be disabled if they meet both of the following criteria:

Six (6) weeks without a login.
Two (2) weeks without seeding.

To prevent inactivity pruning you must visit the site at least once every six (6) weeks or keep something seeding. You can exempt yourself from these rules by donating or reaching 'Teh Fanatic' member class. You can read more about donating by reading here or clicking 'Donate!' at the top of any page.
