Desperately Begging to Skip Concentration or Worse: Simply Ignoring It
Concentration in Dungeons & Dragons is not a method to annoy players, even if it sometimes seems that way. Saving throws must be made to see if a spell can be maintained, and only one concentration spell can be active at a time. This can be cumbersome, but it gives extremely powerful spells like Hunger of Hadar, Protection Spirits, or Wall of Fire a condition to keep spellcasters somewhat in check.
For this reason, many players try to bypass this rule. Begging the DM to waive the concentration mechanic reeks of “I want to throw around power without rules as I please” because of the resulting power explosions.
However, there can be an even worse “exploit” concerning concentration spells: a completely “accidental” forgetfulness.
Yes, amidst various conditions, the order of turns, and a strategy, it can certainly happen that one forgets a saving throw for maintaining their own concentration.
However, it becomes suspicious when this occurs repeatedly, more frequently, and with a brazen obviousness that it can no longer be considered an exploit but rather actual cheating.
Such actions do not make you powerful; they make you a problem. And nobody wants that.
