Normally I wouldn't expect any problems - Wikipedia did it and also some blogs are doing it. However, if the whole site just consists of links (e.g. a web directory) I would be careful.
On how many pages are the 8.000 links? Are the links a main part of the content or almost unimportant (for the content)?
