Will a Yahoo penalty naturally go away once a site is fixed?

I fixed my sites, should I email Yahoo or just wait?

I think I have finally figured out why my sites are penalized; cross-linking. I've now seen the light and am going to remove all cross-linking between my sites. Once I do this I think my sites will finally be in complete compliance with Yahoo's guidelines. Is it still a good idea to email an appeal to Yahoo at the two emails given in earlier threads or is it possible just to wait and get picked back up. I've heard in other forums that some think that once you email Yahoo, they definitively label you as a spammer. Anyone else heard this, or is this conspiracy theory rubbish?
Also, if you think it is a good idea to email Yahoo, how would you go about appealing several sites? In seperate emails or all at once in one email. I have about 15 sites that are all listed in the Yahoo directory in different categories, each with unique content.

Walkman, no it is not just you.
Mine and few other site with penalties have been crawled too recently (see the topic by bcc1234 in this forum)

For me Slurp did not stop but hits from it decreased to be 2-3 page requests max a day for the last 2 days or so.

just noticed that yahoo has reincluded some of my sites again after 2 months absent. I dont know if it was a penalty or what. But maybe it was an update on yahoo's part.

I tried to post a thread. It looks like Yahoo is doing a major update right this moment.
