There are good .info sites there are bad .info sites
There are good .com sites there are bad .com sites
Never say never but it is extremely unlikely any decent search engine will place any weight on a gTLD sites choice of TLD / extension (.com .info, .net, or .org etc.)
But then again, you can expend resources processing dot info domains same as any other domains are processed. So not sure if there is any benefit to singling out a domain for special scrutiny since everything is going to be scrutinized...
But on the other hand, by taking out the .info domains you can maybe speed up the processing of the other domains, and do a shorter routine on .info domains...

Isn't really logical for two reasons
1) By volume there are a lot more .com domains you wouldn't want in your index than there are .info names.
2) The processing power to exclude any domain for other reasons is minimal. Plus once a site is tagged as bad its statistically unlikely to change very often.
(Even if you run a simple crawl and check to see if the content has changed once a month in terms of processing power needed for other tasks (cleaning up and ordering the data etc.) it's minimal.)
