A bad feature is a feature that is not generally accepted in the eMule network. Examples of this are very high ratios (1: 100=bad), credit shaping, automatically taking completed file offline. Some people call these feature illegal, but most they just do not confer to the board rules of http://forum.emule-project.net
Very bad features.
There are also features that hurt the network. Spam, no-upload or no ratio are examples of this.
eMule is released under the [GPL]. Any mod that does not comply with that license is a gpl breaker.
- Not releasing/hosting source. Read this FAQ!
- Claiming you wrote the software without giving credit where credit is due. (see section 2 of the gpl!)
- Linking to the official emule source is not enough. You have to release the full sources yourself!
- Note that a version that does not include sources can have all kind of unwanted spyware/adware/trojans included. This happens more often that you would think!
If you use a leecher modification, it may be detected by other clients with anti leecher detection; so you might lose potential sources when using a leecher mod. There are also those who put all IPs that use a leecher mod in an ipfilter list. You may be branded for a long time if you use a leecher mod.
