There is something irrational in Phuks design. It looks like the designer has some kind of lack in logic, which made him design the site irrationally. It is enough to compare Phuks to Reddit or Voat to see obvious mistakes in interface ergonomics. Also the fact that this site is called Phuks instead of Phux denotes low level in wording creativity. Phuks needs the aid of professionals. Otherwise I don't see a bright future for it.
Looks like it's time to say the proverbial words 'don't feed the trolls.'
Is Phuks perfect ... probably not ... but perfection never happens and functionally it's a great site. I've never been a Redditor, but am known on other similar worlds such as Voat. I very much enjoy it here and see no major flaws. I've also learned in my short time on Phuks that when a flaw is discovered it is quickly addressed. One can't ask for more. And as you noted 'constructive criticism' requires that something constructive be discussed.
BTW, one major problem that all these sites have is that someone comes in, posts a little or even lurks for awhile and then they speak as if 'it's their site' or belongs to their little clique ... they feel they own it and only their opinion counts. I've never looked at it that way myself. Those of you who put your money on the line and write the code for all are the 'owners'. People like myself or our little troll, no matter how active, are simply visitors on someone else's dime. Keep up the good work ... it takes time, but you're building a great site here with a future.
