These are terrible. For example, “uglify” is an uncommon English word and most often means just “to make ugly”. Making something ugly might often involve distorting it, but to promote “distort” as a synonym for “uglify” is very misleading. “Vain” has the original old root meaning of “worthless” but it is almost always used in its figurative sense to describe a person who is "silly, idle, foolish" and perhaps “conceited, proud of petty things or trivial matters". It is also used in the set phrase “in vain” (“without results, to no effect”). Most native English speakers would have no idea what you meant if you used it widely to mean “worthless”. The antique watch was broken and vain. (Incorrect) More on reddit.com

Whereas synonym means 'a word that means the same as another word' and different means 'without similarity'. I see the connection between the words you're trying to make, but conceptual similarity is not synonymous with identical. More on reddit.com
