Block anything that says "1340 Art Magazine" especially on Instagram.
They will tell you that your art is great and that you've been selected to be featured in their next art magazine edition, with homepage and everything. Except they want you to pay around $30 to enter that selection competition, saying the money will be spend on artsy charity.
They have countless bot accounts including bot email accounts.
Do not waste your money on those assholes, nothing they claim to do and be is legit and proven.
