@Miss-Demeanor The existence of how-to guides on the internet does not, by existence, justify the handwaving a roll needed to translate that information into a success. Time to complete the task (a recipe you know by heart is always prepared faster than if you need to keep reading directions), absorption of information, and the ability to translate those instructions accurately are all factors that should not be decided merely by the existence of online how-to guides.
In short, just because there's shit about it on YouTube, doesn't mean it counts as "ghost dots" on a character sheet, thus enabling people to min max their XP in other ways.
Let me give you an example
In RL, I write shell scripts. If you look up sh/bash/ksh scripting in Google, you're bound to find hundreds, if not thousands, of sites that include methodologies, discussions, tips, bad advice, scripting examples, and in some cases, entire guides on how to write scripts. Now, going in, my computer score is in the 3-4 range, and when I go to these sites, it's usually to find an answer as to why some syntax in one string isn't working like I think it should.
I'll take a snippet, test it, see if I like it. I apply it to my current skill and attribute levels to translate it into an action based on what I currently know.
Now, let's say you've never played around with shell scripting EVER
The existence of online guides doesn't guarantee you any form of timely success in understanding functions, variables, syntax, which text editors to use, regular expression, how to do math using code, if/then/elif/fi, for each in, conditionals, loops, etc. Applying those guides to your current level of knowledge will be good experience in raising your skill/attribute levels, but the existence of guides will not result in a solution in a timely, accurate, or immediately useful manner. In the end, even if you plugged together a script after hours of learning shell scripting for the first time, you might come away with a script that echoes commands, but it's sure as fuck not going to be some kind of java-based LowOrbitIonCannon DDoS tool.
Theres guides for making a boat, making knives, guns, bullets, sewing, cooking, fishing, Krav Maga, etc on the internet, but the existence of those only serve to allow practice to (in game terms) raise those skill/attribute ratings to use them effectively.
Some online guides are more within reason, but a GM should take care to not equate a player's ability to think to search for find these guides as a replacement for proper use of skills, especially if the result is critical to anything involving plot or other players.
tl;dr Online guides don't​ teach skill, accuracy, or guarantee absorption of the knowledge. Using 'online guides' ICly for little, non-plot things (bake a cake!) is more acceptable, but cutting corners by citing online guides to handwave dice rolls (by the PC or ST) is lazy and, in my definition, cheating the shortcomings of their XP expenditures. Not everyone can do everything, and online guides are no great equalizer. Online Guides=+1 bonus to existing skill/attr roll, and NOT an excuse to not roll.
