🐾❄🥅#📌♠💦255879

This is a word square:
PAW
ICE
NET
Extract the letters in the positions 2, 5, 5, 8, 7, 9 on a phone keypad to get ACCENT.

⠗⠕⠞⠼⠁⠊⠉:⠺⠠⠰⠶⠮

The first part (before the colon) says "ROT193".
Logically, that's ROT180 + ROT13.
So, do that to everything after the colon - flip it upside down (rot180), decode as Braille, then rot13 it to get ATONE.

∞WᒧO3>H∽UO)Z⊢

Turn your head sideways - it reads as "BELOW VISCOUNT", and the rank below Viscount is BARON.

Start with the section left of the arrow. Those are characters from various languages: SE, MA, PHO, and RE. So we interpret the things right of the arrow as flag semaphore to get COLOGNE.

ĆẸİĿMṈOṖ\$ŦŪVY

You can rearrange these to get ĆOṈ$ŪMṖŦİVẸĿY. The accents there are Morse code for TORI, and "Tori, consumptively" is a crossword clue (though oddly phrased) for DONUTS.

A hot new vow

This is just a cryptic clue for OATH. (Thanks, Sp3000!)

⊔N⌶ⅽ✜ዐᛊfirsts

This says "Unicode firsts", but in a weird way. Take the characters that make up "Unicode", look them up in Unicode, and take the first letters of the official names to get SLASHER.

This is simply a rebus.
Before the minus sign we have SNAIL TACO METRO PEN KEY STOP HATCH. After, we have NAIL COMET OPEN KEYS TOP HAT. Removing the latter from the former gives us S[nail]TA[comet]R[open][keys][tophat]CH, or STARCH.

The middle symbol (that looks like a circled plus sign) means "exclusive or" - basically, overlap and remove anything that's black in both symbols. Do that to the six symbols on either side and you get the word THRASH.

META:…|#/|@…:@**¢#1¢1:/

All the words are made up of a punctuation mark with two letters inserted (or on the sides). For instance, COLO(g)N(e) --> COLON and (t)H(r)ASH --> HASH. Those punctuation marks appear twice each in the text after "META:". Replace the two occurrences with the two extra letters, in order.

You don't like Twitter because it has NOT ENOUGH CHARACTER!
