What is going on? Scammer apocalypse?

Only received 1 so far. Just report them and move on, or even easier, ignore these requests.
Also, swearing isn't censored and isn't against the rules (to a certain point), so... Feel free to swear freely. ;)

Well, I've been bugged by a total of 1 mysterious account, ever, so idk what you're doing.

I tried to start a conversation with the bot, but it seems their only interested in monologues.

I have this too, once or twice/day, during the last 2 weeks now.

I get requests from shady people at least once every few month, I just ignore the majority of them.

You're just unlucky today. It's just statistics. You'll get a random number of adds averaging perhaps 1.5 per day, and some days it'll jump to 0 and others to 5.

This has been going on for months now. Some days I get no adds. Other days 3 or 4.

There's "add my friend here", "explain these photos please", and the newest one, "i am cs:go trade look at screenshot" which is actually .scr file which is actually virus.

I got my first one just the other day, lol. I immediately blocked them.
