@adder, I'm just like you mate with no online presence, except few dedicated medicine and music related forums.
Even stopped visiting TE for years. Was busy with work/ life/ music at weekends.
I went to India for a vacation in 2019, where my wife almost got molested and we spent 2 weeks practically locked inside a hotel room and shared the experience here in TE. Someone told me to post it in Twitter, which I did ( made a twitter account long back and never really used it) since I tagged Czech embassy in India in that post, it got noticed and I started getting threatening messages there.
Went back home and things became normal and forgot about it.
Now Corona came to Europe and one of my friends in India asked me of certain technicalities and requested me to post it in Twitter.
My twitter handle became sort of a early Corona information exchange centre ( mostly doctors were following it and I was following them too)
Now all of a sudden India announced lockdown and believe it or not, most of my epidemiology professors in India were truly shocked and we started discussing the true motive behind the lockdown in Twitter. Akash Banerjee, a YouTuber and a former schoolmate of mine was in that discussion and he understood what we were talking about in medical jargons and made a video on it.
Suddenly one day my twitter followers jumped by thousands and people I don't know started retweeting.
Some started trolling and me and my doctor friends trolled them away ( it was very easy as at that point, India was going through a completely chaotic mess in name of planning, using raincoats as PPE, fooling people with mylab kits, weird, impossible ventilator designs etc)
We didn't hold back and gave the trolls what they deserved.
As the Corona situation got worse I was sent to Spain and I didn't have time to check Twitter. After 3/4 days I tried to login to find my account has been closed. For no reason, I got really upset and made another handle using my secondary email id.
This time I did little bit of homework outside of Indian media reports and simply tore apart ICMR's policy ( it was also very easy as their policies at that time were outrageous with ZERO logic and completely against laws of epidemiology) and criticise Modi and health ministry heavily.
Now the IT cell started working hard. They somehow found my real name, my wife's name, our location, even our kid's name.
They somehow stole some pictures of my wife with her ex boyfriend in some beach of Croatia and made up a sleazy story of her extra marital affairs ( they thought she's an American and accused me of being an anti national, who used taxpayers money for higher education in India and became an US spy)
Now these 3/4 tweets "exposing" us were retweeted few thousand times and was tagged with Lenka's, her sister's and her ex partner's name too.
One fine afternoon she called crying from Prague, I didn't understand what she was talking about till I checked twitter myself.
At this time she was recovering from covid infection ( acquired in line of duty possibly in Poland) going through severe depression resulting in severe drinking problems ( I was in the worst affected area of Spain, our kid was with her parents.
Please understand, this woman is as qualified as I am, earns as much as I do and has got nothing to do with India ( I was the first Indian she met in life) and almost got molested in Delhi for nothing, few months back.
If this is cyber bullying and happens in TE also, I should unsub immediately.
This is what basically IT cell did to us. We don't even talk/ think about India anymore.
After reporting twitter deleted those posts within an hour and blocked 89 accounts over next couple of days. I deleted all my twitter handles and ended up working for ICMR ( my most abrasive post got me that work) for 8 weeks.
