I would start by asking a few questions like:
- how long have you been having those links for?
- have you seen a important decrease in traffic or rankings since you acquired those links?
- is the anchor text the same for all of those links?
- have you experienced traffic and rankings decrease after Penguin 2.0?
You have to make sure first those links hurt you before starting disavowing them. Check your Google Analytics and Google webmaster tools for any warnings or penalties. If everything looks fine I wouldn't do it although I must say that many links looks suspicious.
Keep building links from trusted websites and create useful content, there is no way around it.
