having links will not penalize you, the more links you have, the better it doesn't matter from where. It's just some links our worth more than others. worst case they won't count your links. best scenario you will get ranked higher. Think about it. If you can get penalized by having lots of link, you're competitor can do that and you would get penalized. Only way you would get penalized from having to many links is if your website is brand new and you have built thousands of links.
