Because practicing pickup is hard and actually requires stepping outside of one’s comfort zone, many pickup forums are full of keyboard jockeys, who spend all their time reading about and talking about pickup, without actually doing it.
Keyboard jockeys often have the mistaken notion that they can become PUAs just by reading about it. While reading the material may allow the KJ to actually do a bit better in social situations than if they had not read at all, true pickup is a skill that must be practiced and internalized in the field.
KJs can easily be identified on pickup forums, as they start threads on theoretical questions such as “do girls prefer indirect or direct game?” While these can lead to long threads with different KJs weighing in with different theories and methods, these threads are often just mindless dick crack, which are not beneficial to the true development of a PUA.
I would take anything that Alfredo says with a grain of salt; he’s just a keyboard jockey.
