I live in Ireland so there was always limited advertising on Twitter. There might be the odd campaign but it was blessedly free of ads in general. Then one day I logged in and it was a tidal wave of hot garbage - ads in Turkish, trade fairs in Chinese provinces, African NGOs etc. Just absolutely irrelevant bottom of the barrel dreck every 2 or 3 tweets in the feed. No matter how much I blocked there was more just like it.

I don't know if this was an aberration, a bug or a cynical attempt to screw over advertisers by draining their wallets. I just uninstalled Twitter and used the web version with an ad blocker. I don't even see this shit any more. I wonder if the advertisers are still getting charged though. I hope they are though since paying $$$ for minimal engagement might convince them how worthless the platform is.
