Question: Different threads form a same person with different names?

How can we manage them?

During the last few days
@Rana47 https://www.mapleprimes.com/questions/236758-HPM-Error-Invalid-Input
@SHIVAS https://www.mapleprimes.com/questions/236755-How-To-Run-Or-Implement-HPM-Method-In-Maple
@Madhukesh J K https://www.mapleprimes.com/questions/236747-Error-In-The-Program-HPM

have both asked a similar question on the same topic (HPM) and uploaded both quite the same code (same name of variables, same commands and same syntax errors).
This reveals an obvious close proximity of these three OP.

Given the extreme resemblance of the three threads, my guess is that there is a single person behind those three login names who expects that asking the same question from different login names will prevent the moderators from moving the new thread to an old one, and thus keeping his question in the foreground?

Am I on the wrong track (in which case I humbly ask the three OPs to excuse my words^[1])
If not, how can we prevent this type of behaviour?

^[1] but, as it is likely that they are then close colleagues from the same lab they should coordinate not to ask the same question three times.
