There are many new IDs showing up recently and some of them persistently want me to answer their questions. I understand their eager to build up credit so that their voice can be taken seriously. Here I list several shortcuts to achieve this:

1. donate to OSAIC
this is the fastest and easiest way
2. run a Marathon, post you photo like Eddie did
this is hard, but your credit is permanent after this
3. reveal your old ID
this is very hard if you were a scum
4. read suprathinker's introduction on gauge theory and write a decent comment
this is easy if you are a nerd
