There is an inbound links filter and it has been in use for awhile. So far I can tell you, it does filter links from a single domain or groups of domains. How many links before you trip the filter? I don't have an exact number. The filter seems to be affected by total inbound links/links from a single source. The single source includes insite linking also.
