Iām an annoyed Wordler. Why are some forms of words okay for the answer, but some other forms are not?
For example, the past tense form of a word could be the answer, but apparently never a plural form. 
Also, Iāve gathered that while a past tense spelling of a verb that ends in -ed (such as added, or poked) is not okay, but an alternate past tense spelling (such as froze) is okay. Maybe, though, Iām just misremembering on this one (or on both!).
Redundancy alert!

Ouch. I do not think my brain works that way. At least not after decades of proof reading legal briefs.
The kind with the sentences showing only the bottom half of the words are no problem though
Lol, yes, a proof-readerās nightmare, but still very easy to read. 
Same. I can usually manage with only the tops - sometimes takes a bit more puzzling it out, tho.
I can read upside down stuff V easily. Mom couldnāt. I started reading aloud something that was upside down, and she freaked out. I didnāt know the ability was uncommon.

They certainly donāt make it easy on the proof-reader.
Is he in a comma, I mean coma?
Only works if I read it fast. I get all stumbly if I try to slow down!
This is what was crammed into us at the snooty prep school. I still have my copy, and it also lives on my machine, against memory lapses of the lessons learned between 1978-81.
Looks brutal. I hope you nevertheless split your infinitives and ended sentences with prepositions.
Iām merely human as well, but Iāve always tried to avoid them in my writing. 
I used to do that, until I realized that itās quite all right to boldly go where my English teachers told me not to.
