Experienced enough online drama with smucks to know to carry on regardless, rewardless quietly in the background..., hence never put my hand up here after bad experiences in previous years on other platforms.
I am done ignoring them - because they couldn't ignore me - not even after two years being absent lol.
Don't blame you for being gatvol.
Downvotes should never be allowed to exceed $1 per day with a reason given or the whole system becomes viewed a laughing matter.
Plagiarism is a different matter, person should be notified, given a month to rectify, when not correcting account should be blocked/banned.
