Sometimes donors misuse the tribute information section of the OLX form. Often, they do so to be sweet, such as saying that their gift is in honor of your amazing and dedicated staff. And while the sentiment is nice, processing the gift requires that I create a useless tribute record for the "dedicated and amazing staff." I could bypass the whole issue if I could just remove that tribute information.
This (and the fact that we had very few tribute gifts overall) is why I set up Gift Attributes for OLX to use for tribute gifts and turned off the built in feature at my last org.
