"When my memes gets an upvote.": This violates subject-verb agreement.
"Subjects and verbs must AGREE with one another in NUMBER (singular or plural). Thus, if a subject is singular, its verb must also be singular; if a subject is plural, its verb must also be plural. In the present tense, nouns and verbs form plurals in opposite ways: nouns ADD an 's' to the singular form; verbs REMOVE the 's' from the singular form."
As such, this should read, "When my meme gets an upvote," or "When my memes get an upvote."
